There's always advantages and disadvantages to doing any role. And there's a great sense of achievement, testosterone, fun, being able to live out your masculinity when you play an action role, or an action-adventure, or a real tough-guy role. Really, if you're doing a comedy, you can sit back and relax. And it's good to know that at the end of the day, you don't have to run off for another two hours and go to the gym, or go spend the rest of the night swordplaying with stunt guys. Then I think, "Oh my God, I love comedy.".

The thing about courage is it’s something that we have to learn and relearn our whole lives. It’s not just in you, it’s in every choice we make every day.

I do get stressed at times, but I love what I do as an actor. This is the part that I don't like. I don't actually like talking about - I wish I could just go and get on with my job, because I love getting a script, breaking it down, working with other people, bonding with other people, fighting with other people, and out of those arguments, creating something that nobody expected and seeing it all come together. Telling a story, having an impact on people's lives, moving them and making them laugh.

The truth is never pretty.

My problem is, whether it's for emotion or for the talents that a character has to have in a role, I find it very difficult to not take on a challenge. I need to say, "Okay, enough, take the easy road." But the easy road for me is not - it might just come out coincidentally. I wouldn't ever choose a movie because it's easy. I might choose a movie because I feel like being funny, or I feel like being able to do something that is perhaps dramatic, but to a lesser degree. Because I like switching it up, basically, not because I would take the easier road.

When I went to Scotland to do another movie, I would sing with a coach up there and then when I went to New York I sang with a coach over there-I mean I've now sung with coaches in LA, New York, London, Glasgow, St Louis and Rio de Janeiro!

Comedy is actually very hard. It's hard to choose those moments and know when you can really push it, and know when you should be bringing it back and making it more subtle, and knowing as time goes on, as you do take after take and the crowd around you stops laughing. Whenever you do comedy, you realize you're up against - you're performing next to people who you would think are so unbelievably good at it, that that's a bit of a pressure. But at the same time, it's just fun. It's fun to be able to let out that side of you.
