Young Guns’ Leading Heartthrobs: See How They’ve Changed

For audiences who grew up on late-1980s and early-1990s cinema, few movies left a mark quite like 1988’s “Young Guns” and its 1990 follow-up, despite the mixed critical response both films have received over the years. The movies assembled a memorable cast that included Emilio Estevez, Charlie Sheen, Kiefer Sutherland and Lou Diamond Phillips while giving the classic Western a modern edge. They also reimagined the stories of real-life outlaws, most notably Billy the Kid.

Nearly 40 years after the first film arrived, interest in “Young Guns” has surged again. The cast recently reunited at Fan Expo Dallas, while Estevez continues to say that a third chapter, “Young Guns: Dead or Alive,” is in development with him attached to direct. Whether that long-discussed sequel ultimately reaches theaters remains uncertain, but the legacy of the original Regulators is firmly established.

Time has also transformed the performers who brought this alternate version of the Old West to the screen. The young actors once associated with Hollywood’s rising class have since become established stars, respected veterans and, in some cases, entertainment legends. Here is a look at where the principal “Young Guns” cast members are today.

Emilio Estevez played William H. Bonney, better known as Billy the Kid, the youthful gunslinger at the center of both “Young Guns” movies. When he joined the project, Estevez was already a leading figure of 1980s Hollywood thanks to films such as “The Breakfast Club,” “The Outsiders” and “St. Elmo’s Fire.” He was also firmly identified with the era’s Brat Pack.

After his Brat Pack success, Estevez was thrilled to secure the Western role. “At the time, I owned a house in Montana, so I was around horses and guns. So for me, the opportunity to get on a horse and actually get paid for it, and play this historical character, [was great],” he told Yahoo! Entertainment in 2023. He said he “lobbied hard” for the part, ultimately winning it despite not being the production’s first choice.

Now in his mid-60s, Estevez has built an accomplished career behind the camera as well as in front of it. His acting work became less frequent during the 2010s, although he returned to one of his signature characters, Gordon Bombay, in the 2021 Disney+ series “The Mighty Ducks: Game Changers.”

Kiefer Sutherland already carried a famous Hollywood name when he joined “Young Guns,” having appeared in mid-1980s films including “Stand by Me” and “The Lost Boys.” He is the son of “Ordinary People” and “M*A*S*H” star Donald Sutherland. In the Western franchise, he portrayed Doc Scurlock, a hesitant gunfighter, devoted friend of Billy the Kid and the Regulators’ inexperienced “tenderfoot.”

Sutherland has often described the first “Young Guns” as a particularly meaningful experience, thanks in large part to the bond formed among the cast. “The first ‘Young Guns’ was the most fun I’ve ever had on a film,” he told The AV Club in 2016. Having left school at a young age and never attended college, he said the film gave him the chance to spend his evenings with “six really great friends,” adding that the group was exceptionally close and had an unforgettable time together.

Sutherland went on to become one of the busiest members of the “Young Guns” ensemble. His defining television role arrived in 2001, when he began playing counterterrorism operative Jack Bauer on Fox’s “24.” He later starred in the ABC-Netflix drama “Designated Survivor” and remains active in major screen projects as he approaches 60. In the upcoming film “Father Joe,” he plays an armed renegade priest who takes on the Manhattan mob.

For Lou Diamond Phillips, “Young Guns” represented a major turning point. “Not until I stepped on that set did I go, ‘I’ve arrived,’” Phillips said on “The Rich Eisen Show” in 2026. Sharing the screen with Estevez, Charlie Sheen and Sutherland—actors he admired—made him feel like a “brown Brat Packer,” or, as he put it, “Brat Pack-adjacent.”

Phillips had already made an impression as Ritchie Valens in 1987’s “La Bamba” and Angel Guzman in “Stand and Deliver” the following year. In both “Young Guns” films, he played José Chávez y Chávez, portrayed as a stoic and fiercely loyal cowboy of Mestizo and Navajo descent who joins the Regulators after the killing of John Tunstall.

As with Sutherland, Phillips has maintained a remarkably steady workload since becoming widely known in the 1980s. Now in his mid-60s, he supplied a voice for the 2026 Netflix animated series “Stranger Things: Tales From ’85.” His other notable credits include the 1996 war drama “Courage Under Fire” and the A&E-Netflix series “Longmire,” which ran in 2012.

Before the “tiger blood” era, the viral “Winning..!” tweet and his widely publicized HIV diagnosis, Charlie Sheen ranked among Hollywood’s biggest stars. The son of actor Martin Sheen and younger brother of Emilio Estevez, he broke through with films such as “Platoon” in 1986, “Wall Street” in 1987 and “Major League” in 1989. In the first “Young Guns,” Sheen played Dick Brewer, a ranch foreman who became one of the Regulators’ early leaders.

Sheen later reclaimed the spotlight as the star of CBS’s hit sitcom “Two and a Half Men,” which dominated much of the 2000s. His marriage to Denise Richards also drew intense media attention. His time on the sitcom ended amid a series of off-camera controversies, though the publicity helped drive ratings. In more recent years, Sheen has appeared to enter a period of rehabilitation and reflection, with his rise, collapse and attempted comeback explored in the 2025 documentary series “aka Charlie Sheen.”

“This wasn’t a giant mea culpa,” Sheen said of the Netflix series. “These are the areas where everybody’s been radically misinformed for so long that now I get an opportunity to deliver the stories as they happened, [in the] first person.” Sheen is also entering the wide world of celebrity podcasts with a new show titled “Mostly Sheenius,” according to The Hollywood Reporter.

Dermot Mulroney is now a familiar presence in film and television, but “Young Guns” gave him one of his first significant movie roles. He played the Regulators’ abrasive and prejudiced member, “Dirty” Steve Stephens, bringing the character to a much wider audience. Mulroney’s social media activity also helped propel news of the cast’s Fan Expo reunion.

“PALS since 1877,” declared Mulroney in an Instagram post following the crew’s 2026 reunion. “Turns out we all have different sides of the same memories! Laughed our asses off this weekend. When @kiefersutherland says ‘never had more fun on a movie’ #youngguns you know you had some fun!” Mulroney’s post included a carousel of photos with several of his “Young Guns” co-stars, much to the delight of longtime fans.

Now in his early 60s, Mulroney continues to project the screen presence of a leading man while maintaining a steady stream of high-profile work. Following “Young Guns,” he appeared in films including 1997’s “My Best Friend’s Wedding” and 2005’s “The Wedding Date.” More recently, he played Battalion Chief Dom Pascal on NBC’s “Chicago Fire” and in related entries from the “One Chicago” franchise. His former marriage also attracted attention because of the couple’s notable age difference.

Although “Young Guns” and “Young Guns II” are packed with gunfights, Casey Siemaszko’s Charlie Bowdre was portrayed as more enthusiastic about throwing punches than drawing a weapon. Siemaszko also delivered one of the franchise’s most recognizable speeches, a scene that later found an unexpected second life in hip-hop. Warren G sampled Bowdre’s declaration—“Regulators — we regulate any stealin’ of his property. We’re damn good, too!”—for the song “Regulate” with Nate Dogg, which climbed to No. 2 on the Billboard Hot 100 in 1994.

Viewers may also remember Siemaszko as one of Biff Tannen’s henchmen in the “Back to the Future” films. He appeared alongside Kiefer Sutherland in “Stand by Me” and led the 1987 teen comedy “Three O’Clock High.” Known for keeping a low profile, Siemaszko has made relatively few screen appearances in recent years, aside from guest roles on shows such as NBC’s “The Blacklist” and Showtime’s “Billions” during the mid-2010s.

Siemaszko is now in his 60s, and his most recent credit listed on IMDb at the time of writing is voice work for Rockstar Games’ “Red Dead Redemption II.” Despite his limited public profile, he attended the “Young Guns” reunion at Fan Expo Dallas.

Terry O’Quinn is best known to many viewers as John Locke on ABC’s “Lost,” a performance that earned him a Primetime Emmy between 2004 and 2010. Long before that acclaimed role, however, he appeared in “Young Guns” as Alexander McSween. The quiet, principled attorney uses his legal standing to help the Regulators become deputized following John Tunstall’s murder.

Despite being one of the older surviving cast members, O’Quinn — who’s now in his mid-70s — continues to astound fans with his seemingly unchanged appearance. “Terry O’Quinn must be on that same vampire potion Paul Rudd is on. He doesn’t age!” commented one fan on the aforementioned Instagram post from Dermot Mulroney, which included a snap of the former “Lost” star. “That’s what I was thinking too lol,” added a second commenter. “He looks so young.”

O’Quinn is still making waves as a working actor, too. In 2026, he provided the voice of Richard in the video game “Silent Hill: Townfall.” He has also played the recurring role of Peter Bach in the 2021 Syfy-USA Network series “Resident Alien” and Byron LaCroix in the 2020 CBS procedural “FBI: Most Wanted.” His IMDb page boasts credits dating all the way back to 1980. 

Christian Slater’s breakout role came in Michael Lehmann’s “Heathers” when it hit theaters in 1989. Although he could have fit right in with the rising stars of the original “Young Guns” film the year prior, he stood comfortably alongside the series’ stars after being tapped to play a member of Billy the Kid’s new gang, “Arkansas” Dave Rudabaugh, in “Young Guns II.” Like “Dirty” Steve Stephens before him, Slater’s Rudabaugh is effective in a fight but is always looking out for No. 1.

Between “Heathers,” “Young Guns II,” 1990’s “Pump Up the Volume,” 1991’s “Robin Hood: Prince of Thieves,” 1993’s “True Romance,” and other period projects, Slater was one of Hollywood’s most in-demand actors during the early ’90s. Now, three decades on, he continues to shine in more mature roles in films and on television as a performer in his late 50s.

Slater was announced as a new cast member of the Apple TV+ series “Shrinking” in 2026. He also joined actor-comedian Jenny Slate to portray a hectic morning routine in a Cole Haan advertising campaign. His recent film and television projects include the 2024 Paramount+ with Showtime series “Dexter: Original Sin” and Roku’s adaptation of “The Spiderwick Chronicles.”

A low-key star of the 1980s, Alan Ruck claimed a permanent spot in the pop culture zeitgeist with his performance as Cameron Frye in the 1986 John Hughes classic “Ferris Bueller’s Day Off.” The following year, he starred alongside Brat Pack-adjacent talents Charlie Sheen and Kerri Green in “Three for the Road.” He played Hendry William French in “Young Guns II,” who joins the Regulators’ cause after losing his farm and wife.

When a reporter from The Guardian called Ruck out for downplaying his “Young Guns II” credit during a 2021 interview, the actor responded in delightfully self-deprecating fashion. “You know I was just the widower in that movie, right?” Ruck joked to the reporter. “You don’t want to be the sad, sorry guy in a western – you want to be the guy who rides his horse through a plate-glass window and shoots everybody!”

After “Young Guns II,” Ruck’s run of on-screen success continued with a litany of memorable film and television projects. He played Captain Harriman in 1994’s “Star Trek: Generations” (which dropped the same year he starred alongside Keanu Reeves in “Speed”), was a cast member on ABC’s “Spin City” from 1996 to 2002, played Connor Roy on HBO’s “Succession” from 2018 to 2023, and has continued to stack film and TV credits. In 2026, the 70-year-old appeared in multiple episodes of the HBO Max series “Rooster.”

Like Christian Slater, Balthazar Getty played one of the new Regulators in “Young Guns II,” namely, Tom O’Folliard. The film’s version of O’Folliard is that of an orphaned teenager who becomes infatuated with the Billy the Kid mythos through reading dime novels. Despite his age, Billy ultimately allows him to become the youngest of his gang’s new additions.

Getty, who’s a member of the Getty family that became one of the world’s wealthiest via the mass media and petroleum industries, also starred as Ralph in “Lord of the Flies” the year that “Young Guns II” was released theatrically. Since then, he has been a star of the big and small screens, working with David Lynch on 1997’s “Lost Highway” and Showtime’s “Twin Peaks” revival (in 2017) and serving as a main cast member on ABC’s 2006 series “Brothers & Sisters.” He has also dabbled in music. More recently, he appeared in Francis Ford Coppola’s 2024 take on “Megalopolis.”

Along the way, he worked to distinguish himself from his famous family. “I struggled with it a lot as a kid and overcompensated,” he told People in 2014. “I didn’t ever want to be labeled a rich kid, because I wasn’t. The structure of how [family trusts] work didn’t allow me to be at that point. It was very ironic, this assumption made by people coupled with the fact that I had a very tough upbringing.”
