It was dangerous stuff. We were running on top of moving trains. We got to do amazing things. I like doing stuff like that. I enjoy it. But believe me, there were things that were so dangerous that I wasn't touching them.

The older I get, the more vegetables I eat. I can't stress that more. Eating healthy really affects my work. You not only need to be physically prepared, but mentally and spiritually.

The physicality was important to me. Because the film has Shane Black's dialogue, and [Robert] Downey's delivery, and you look at [Jon] Favreau, Don Cheadle and Gwyneth [Paltrow], it is this heightened level with a comedic aspect to it. Everything is grounded in reality, but it plays a little heightened.

Not every conspiracy is a theory.

I want to show up to work and take risks. I don't ever want to play it safe.

I can't go to the hardware store, cut a sheet in half and staple it to the window anymore. It doesn't fly.

The biggest regret I have about 'Rubicon' is that we didn't end it. Sometimes you do these shows and you don't have the opportunity to get closure. Stories are supposed to have a beginning, middle and an end.
