Mac’s ‘Strong Faith Sustained Him’—Actor Gary Sinise Shares Moving Tribute to Son Who Died From Cancer at 33

Award-winning actor Gary Sinise, who is well known for his roles in “Forrest Gump,” “Apollo 13,” and “Truman,” posted a moving tribute to his son Mac, who died from a rare spinal cancer called chordoma on Jan. 5 at the age of 33.

Sinise, who played the father of contemporary Christian music (CCM) singer-songwriter Jeremy Camp in the Erwin Brothers‘ film “I Still Believe,” referenced his faith in his tribute to his son.

“Like any family experiencing such a loss, we are heartbroken and have been managing as best we can,” Sinise said. “As parents, it is so difficult losing a child. My heart goes out to all who have suffered a similar loss, and to anyone who has lost a loved one.”

Mac’s battle with cancer lasted over five years, a fight that Sinise described as “more and more challenging as time went on.”

“While our hearts ache at missing him, we are comforted in knowing that Mac is no longer struggling, and inspired and moved by how he managed it,” the actor added. “He fought an uphill battle against a cancer that has no cure, but he never quit trying.”

Sinise said, “I am so blessed, fortunate, and proud to be his dad.”

Mac worked at his father’s foundation as the Assistant Manager of Education and Outreach, and although his cancer paralyzed him from the chest down, he used his limited mobility  to continue serving wounded veterans of the military.

Mac also recorded an album titled “Resurrection & Revival.” The album was a passion project of Mac’s and was finished in the last year of his life.
