Avengers: Infinity War - 12 Behind-The-Scenes Secrets You Need To Know

12. Robert Downey Jr Can Do What He Wants

If you're the guy on whose shoulders the entire MCU was built, you can definitely expect some special treatment. If you're Robert Downey Jr and you're in the super-privileged position of knowing exactly how much the studio need you (given that you were basically allowed to write your own contract), that special treatment is on an entirely different level.

And boy did he take advantage. Apparenlty, the Iron Man star requested that all of the furniture in his house in LA was shipped to the set in Atlanta. He got his wish.

On top of that, he also apparently refused to wear a full-body motion capture suit (as Tom Holland had to). Instead he wore his Iron Man breast plate and black trousers and trainers, which would be digitally replaced for the final film. He says "they tried to get one of these on me, but no" and that he "wouldn't be caught dead in one."
