Michael Biehn’s Onslaught Role Explained: Why It Matters

Contains spoilers for “Onslaught”

Bring up the defining sci-fi and action stars of the 1980s, and the same heavy hitters usually dominate the conversation: Sylvester Stallone and Arnold Schwarzenegger, with Harrison Ford occupying his own adjacent legend status, followed closely by Kurt Russell and, a tier below, names like Dolph Lundgren and Jean-Claude Van Damme. Yet that familiar roll call often leaves out one of the decade’s most essential genre presences. Michael Biehn may not have always been the marquee name, but his impact on ’80s action cinema and science fiction is undeniable. Best remembered as Kyle Reese in “The Terminator” and Corporal Dwayne Hicks in “Aliens,” Biehn now returns in Adam Wingard’s “Onslaught,” a deliberately retro action-horror movie that channels the same muscular, high-tension spirit of that era.

In “Onslaught,” Biehn appears as Baylor, the man overseeing a covert military installation where Dr. Kammler, played by Dan Stevens, is engineering a new breed of supersoldiers. Baylor answers to an unnamed and shadowy “board” about the progress of the operation, though his role in the chaos is short-lived. He meets his end alongside Kammler when the soldiers break free. Even with limited screen time, Biehn makes the most of the part, delivering the kind of hard-edged, no-nonsense dialogue that reminds viewers why he remains such a beloved figure in classic sci-fi action movies.

For director Adam Wingard, casting Biehn was more than a nostalgic flourish — it was personal. In the film’s press notes, Wingard shared just how deep his admiration runs: “In sixth grade, my friends and I created a Michael Biehn fan club,” he said. “We just thought he was the absolute coolest actor, and he was what we all wanted to look like. I used to slick my hair back to resemble his hair in ‘Aliens.'”

It’s also worth remembering that one of the most quoted lines in the “Terminator” franchise did not originate with Arnold Schwarzenegger. In James Cameron’s original “The Terminator,” it is Biehn’s Kyle Reese who first says, “Come with me if you want to live,” while Schwarzenegger’s famous use of the line in “Terminator 2: Judgment Day” functions as a later echo. Biehn’s Cameron collaborations also include his memorable turn in 1989’s “The Abyss,” and his career continued strongly through the 1990s with major supporting and starring roles in films such as “The Rock,” “Tombstone,” “Navy SEALS,” and “K2.”

Biehn hasn’t had as many major big screen credits recently, but he’s stayed active with a wide range of action movies or thrillers, including Robert Rodriguez’s “Planet Terror” in 2007, and just last year, a voice role in “Predator: Killer of Killers.” He’s had a few high-profile guest turns on TV in the 2020s, appearing as mercenary Lang in “The Mandalorian” and survivor leader Ian in “The Walking Dead,” the latter of which earned him a Saturn Award nomination (Biehn won a Life Career Award from the same institution in 2011).

His character in “Onslaught” is classic Biehn — the scowl, the swagger, and the one-liners. The actor has featured in a number of explicitly ’80s-inspired projects over the years, like when he voiced the main character in the 2013 sci-fi video game “Far Cry 3: Blood Dragon.” And yet, he still rarely gets the credit of his contemporaries in the genre. Given how explicitly “Onslaught” shows love to “The Terminator” and “Aliens,” his inclusion is a well-deserved nod.

Michael Biehn isn’t the only element of James Cameron’s ’80s oeuvre that can be seen in “Onslaught.” Everything from the synth-heavy soundtrack, to specific bits of cinematography, to the high-caliber slasher horror/action genre blend point back to Cameron and other superstar filmmakers of the era. It even has the protective mother-daughter framing that emerges midway through “Aliens.”

In the official press notes for “Onslaught,” Adam Wingard says that his goal was to create “a really crazy, violent action-slasher film that’s paying homage to John Carpenter and James Cameron.” Even if you didn’t know that going in, it’s pretty clear from the jump. There was an era when shooting a semi-truck full of gun-toting baddies blasting down a desert highway at night was a sort of genre unto itself, and “Onslaught” believes, correctly, that we still need that vibe every once in a while.
