Gary Sinise Details Leaving Hollywood Amid Son’s Cancer Battle

When Mac passed away in 2024, Gary found solace in knowing his son was at peace in the end.

“He was graceful in accepting what was happening to him,” he said. “And I saw him smile a whole bunch in the hospital before he couldn’t smile anymore.”

While Gary—also dad to Sophie Sinise, 36, and Ella Sinise, 33—and his family are still mourning the loss, they are keeping Mac alive through his music, with the Emmy winner expressing that he felt “blessed” that his son had such a gift.

“I want people to hear his music,” he said. “I want people to share it. I’m on a mission.”

With his Hollywood life behind him, Gary’s found contentment in his new home of Tennessee. And for now, he has no plans to leave, especially as he takes on his latest role of “papa” to his five grandchildren.

“I haven’t been back to work since 2019,” he shared, adding that when it comes to his acting future, “It’s possible, something may come along and it’ll be right, but it’s harder to leave home now for long periods of time because I just want to be around the family.”
