"I'm still in the film industry," he told ET. "I'm now producing, directing, editing and writing. There's a film out right now called Don't Blink that I produced with Mena Suvari and Brian Austin Green. It's on Netflix."

Ian Petrella, who played Ralphie's little brother Randy, is now a puppeteer living in Ohio.

"There is a scene where Randy gets thrown down the slide, and he's terrified and you're thinking, 'Wow! You are really good!' No, I'm just really scared," Petrella, 41, told ET. "It wasn't the most stable of sets. It wobbled a lot."
