I wanted to be a cartoonist. I was one of those kids who sat around and drew in my room all the time.

I think Aaron [Sorkin] did a remarkable job of plucking Andy [Hertzfeld] out of [Steve] Jobs' story, to perhaps reflect back on Steve a sense of maybe some things that were missing in Steve's life. Andy, just by nature, is one of these straight shooters.

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

I had a great time working with Denis [Villeneuve] and the whole group. It was a very different kind of a part [in Story of Your Life] than I've played in a while. But I had great fun; and yes, it was really nice not to have to answer to anybody about that.

The next film I have is called Miles Ahead, which is about Miles Davis, during a five-year period in his life during which he's struggling to figure out which direction to go musically and in his life. I play a record executive who's there to try to get Miles to collaborate with one of my clients. I'm excited to see that.

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.

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.
