The flying sequence, where he’s testing out the boots, that was a huge deal for us. I’d been prepping for that and training for that moment. It winds up being maybe a minute and a half in the movie. We really felt like that was the thing, that’s where Iron Man achieves something no-one has ever done before. And he does it alone and we felt that was really important. I felt like we delivered something that was more than what was just expected on the call sheet.”

Staying balanced and focused for the entirety of the shoot. I wanted to push the envelope and I wanted to feel good at the end of every day if possible.”
