This interview with Kevin Bacon
about The Woodsman
really gives you a sense of what a crafted, passionate actor he is. It wasn't a role he was looking for, he wasn't even reading the script looking for a part, and he fell in love with it. It's fascinating to hear what it's like for him to work with a character he doesn't like and wouldn't ever want to be.
Of course few actors are Kevin Bacon, but it's something to aspire to.
