He’s stepping back. 

“CSI: NY” star Gary Sinise stepped away from Hollywood after his son Mac’s tragic death. 

“Something may come along and it’ll be right, but it’s harder to leave home now,” he told People in an interview published Wednesday. 

“I just want to be around family. Since losing Mac, I hold my daughters a lot tighter. You think about the things that are really important.”

The son of the actor from “Forrest Gump,” McCanna – also known as Mac – passed away in January 2024 at the age of 33 after fighting chordoma, a type of cancer, for 5½ years.

Sinise and his wife, Moira Harris – the couple has been married since 1981 — also share daughters Sophie and Ella, and have five grandchildren. 

Sinise, who has won an Emmy, a Golden Globe and a Tony, is also known for “Forrest Gump,” “Apollo 13” and “The Green Mile.” 

In addition to this tragedy, Sinise’s wife also battled Stage 3 breast cancer, which she managed to overcome. Sinise revealed that dealing with his wife and son’s health struggles has been a tough challenge that he has been facing since 2018.

In 2020, when Mac was hospitalized for six months, Sinise stepped away.

“That’s when I stopped acting,” Sinise explained. 

“I started putting everything I had into trying to find a miracle for Mac.”

The “Apollo 13” actor said he leaned into his Catholic faith during his son’s cancer battle. 

“Hope keeps you in the fight. You could see tumors on his body. You knew the drugs weren’t working. But I wasn’t thinking we were going to lose him.”

Sinise added, “He didn’t want to go. But I know Mac was at peace at the end. He dealt with it with grace and courage.” 

Since Mac’s death, Sinise has shied away from the spotlight and spent time with his family in his Tennessee home. 

“Mac left us things that are beautiful,” Sinise said, referring to how his son was a musician and composer. “I want people to know who he was.” 

Sinise has been working to release his late son’s music, and hopes to see a live orchestra perform it, he said. 

Sinise expressed his desire for people to listen to his son’s music and share it widely. He emphasized his commitment to this mission by stating he plans to prolong his son’s projects for as long as possible even after they are completed.
