He doesn't look a lot like Steve Jobs, but I think people tend to focus too much on that aspect. To me at least it's not very important. It's about his life, which is supposedly interesting enough to justify a movie, not about how the individual people looked. Once you are over the fact, it just doesn't matter. Look at Jesse Eisenberg as Mark Zuckerberg. I mean, he has curly hair, that's about all similarites they share, still, nobody cared. Even Noah Wyle as Steve Jobs wasn't quite as close as people are remembering. It's much more about acting, how they talk, move and so forth. The rest is up to suspension of disbelief anyway.
