Robert Downey Jr. loves to eat, especially on the set, where lunches are cancelled one after another due to endless filming. One day, Robert thought that he was experienced enough to improvise with food. So, he often appeared on camera with food, which he ate right during filming. It's funny that the first few times the film crew thought that the burger in Tony Stark's hands was according to the script.

Robert Downey Jr. bringing his own snacks to set is just so Robert Downey Jr.! 🍔😄 Love his improvisation skills both on and off camera! 🎬
