The key research I usually apply that allows me to understand the roles that I take on, starts with the script in front of me, and what it offers. I try to absorb as much of it as I can, in the time that I have to study it, and I like to change things up, if I have a choice in the matter... and I usually don't. I dream on it, write about and find out who the individual is, and try to bring him to life with as much human and truth as I can.

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've done a lot of theater work that has been quite diverse. I feel very fortunate to have had many different people think of me in many different ways. So, as an actor that's all you - all I want is diversity. So far in film and television work I have done has not been as diverse, and I hope it grows to be.

I'm always trying to remember that kindness goes a long, long way. I think that's something that people will definitely take out of this film as well.

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.

To see those two characters [Steve Jobs and Andy Hertzfeld ] juxtaposed against each other shows an interesting dynamic of how gifted people might function differently in the world.

Things never go the way you expect them to. That's both the joy and frustration in life. I'm finding as I get older that I don't mind, though. It's the surprises that tickle me the most, the things you don't see coming.
