Lou Ferrigno is a busy guy. The former pro bodybuilder and actor (best known for his role on The Incredible Hulk) is working on five new movies, but he still made time to watch his son, Lou Ferrigno Jr., on 9-1-1 when he could.

Ferrigno Jr., 40, portrayed firefighter Tommy Kinard on the hit Ryan Murphy procedural.

“I [watch him] when I get a chance,” Ferrigno, 73, told Us Weekly exclusively at The Hollywood Christmas Parade supporting Marine Toys for Tots. “I have five movies coming out that I’m very excited about. I’m happy for everybody.”

9-1-1 fans know that, starting in season 7, Tommy was Evan “Buck” Buckley’s love interest. He was Buck’s first same-sex relationship before the two broke up midway through the current season 8.

“There’s pride and there’s a want to do good, obviously, and for [Buck] to be representative in a positive way. But I don’t put too much pressure on myself,” Oliver Stark, who plays Buck, exclusively told Us Weekly in October. “Somebody called me a ‘bisexual bi-con’ in an interview last year, which I kind of loved. But when I’m in my day to day at work, I don’t think of it in those regards.”

Ferrigno admitted he is rooting for his son’s character to make his relationship work.
