For a man, there's a big responsibility that comes with having a boy because men are made by their fathers. If you've got a good productive man around it's better. I have such a close relationship with my dad and that responsibility to produce a good man is something I think about.

You do stuff that gets a reaction and you think 'that's a winner' and then it never sees the light of day. But the thing with improvisation is that 90% of what you come up with won't be used and for good reason. But you keep going for the occasional gem that you might come up with. You do a scene and a lot of the time. We wouldn't cut. So, you come up with something that might be funny and then you go, 'alright, what else'? So, you kind of throw stuff against the wall and see what happens. But you've got to be prepared to make a fool of yourself.

In any kind of comic scene you're going to perhaps push the boundaries of plausibility but as long as there is some semblance of logic I think as an audience you'll buy it and as an actor, when it comes to playing things like that, it gives you something to delve into. When I don't buy into a comic scene is the type of scenario where you'd just go: "Well, that would never happen."

Because I was always a fat child, I got fatter and fatter, and I ended up 18 stone and with a 40-inch waist.

As an actor, you try and be cool, but one of the reasons you become an actor is because you're a film fan. And then you're like, 'Oh my god, Ridley Scott just spoke to me!'

There's nothing so unattractive as vanity... particularly male vanity.

Every audition I get, I agonise over and I put everything I can into it.
