I think a lot of the instincts you have doing comedy are really the same for doing drama, in that it's essentially about listening. The way I approach comedy, is you have to commit to everything as if it's a dramatic role, meaning you play it straight.
'3:10 to Yuma' was one that I just kept on talking and thinking about after reading it. And I think the reason is because, like in most Westerns, you have the very clear-cut bad-guy/good-guy, however, as the movie progresses, you kind of see that it's a very fine line that divides these two.
