If you're a casting director, you're going to be curious to see what Timothy Spall's son is like. But when you get in the door, you have to have something to offer.

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

Doing Prometheus was what you imagine being an actor is like when you're five. In a spacesuit, on another planet, getting killed by an alien. It was a real treat, it felt like being a part of movie history.

My dad's one of the funniest men in the world. I grew up with him making me laugh so much I'd beg him to stop.

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.

I was nervous about playing a lead part in a Working Title romantic comedy and I was also nervous about the fact that I not only had to take my clothes off, but get my willy out. There's certain things you can do to make yourself look better, but there's nothing you can do about your willy. Your willy is your willy and no amount of working out is going to make your willy look any different. You get what you're given. But I wanted to look my best and to whip myself into any semblance of handsomeness. And that was hard going.
