I got to meet Andy [Hertzfeld], and he sort of opened his life to me. He showed me Palo Alto and we had food together and I met his wife and saw his home. We talked a lot about his experiences, and I just tried to absorb as much about him as I could.

Andy [Hertzfeld], just by nature, is one of these straight shooters. A very moral guy, kind of an open book. Along with being brilliant and one of the original members of the Macintosh team, he has a really generous spirit.

I play Edward G. Robinson [in Trumbo], who was a close friend and a co-worker of Dalton's [Trumbo]. They worked together on at least one or two screenplays. A lot of these stories take famous people and show you who they are behind the scenes, which is kind of fun. One of the things about getting to play Edward G. Robinson was learning who the man was away from his movie-star exterior.

Most of the people in New York are very often from somewhere else.

Film, for me, has been a process of learning on the job.

Also to get to see over the course of time how they change, and how Andy [Hertzfeld], regardless of how he's treated, still maintains a friendship with Steve [Jobs] over the course of time. Enough to want to show up and cheer him on. It says a lot about his character, and also that he cares about Steve. Yeah, I find it moving, and I find it a lovely thing on Andy's part.

I think in regards to [Andy Hertzfeld ] relationship with Steve [Jobs]... Andy is a brilliant guy, and loves Steve with all his heart. I think he would have loved to work with him even longer. But the circumstances just weren't right for him.
