best big name actor in Hollywood

I just started watching House of Cards and not to my surprise, I am blown away by Kevin Spacey's performance. I have grew up on many of his films over the years.

This guy I consider the best big name actor Hollywood. Everything he is in he can put on a flawless performance, really making his roles and characters believable. Where most actors of his tier these days are just in it for the spotlight and attention, this guy seems to genuinely like acting and putting on a good show. Even his voice work is great, Call of Duty and Moon and he can put on a performance without even really being on screen. Great actor.
