Peter Billingsley (Ralphie from A Christmas Story) was an executive producer on Ironman!
Billingsley is one of the Favreau/Vaughn repertory players. He played an uncredited elf in Elf. He had a larger role in The Break Up. I think he had some screen time in that stand–up movie that they did (last year?).
Yeah, it always kind of gooses me when I recognize him on–screen. I always want to shout, "Ralphie!" But I don't. Instead I elbow whoever is next to me and tell them. And then they're like, "I care?" And I'm like, "You should!" And they're like, "Who are you?" And I'm like, "Alex Knesnik, nice to meet you." and I offer my hand. And they're like, "Go away, creep." And I'm like, "Can I have your popcorn?" And they're like, "Security!" And I'm like "Some people. Can't hold their liquor." And they're like, "Punch!" And I'm like, "Ow!" And they're like, "Kick!" And I'm like "My liver!"
I could go on, but I think you got the idea; I'm suing Peter Billingsley for mental distress.
