Jack Perry, son of late actor Luke Perry, says he’s “very proud” of his dad’s final big-screen role in Quentin Tarantino’s new movie “Once Upon A Time In Hollywood.” Jack not only worked on set as a production assistant, but he also makes a cameo in the film alongside his late father. “My dad was really proud of it and really excited about it, I’m glad he got to do that,” Jack tells Entertainment Tonight.
