I stay away from Speedos. That would cause me absolutely unnecessary publicity.

With everything you do as an actor, you obviously know the full story. But the person watching it doesn't, necessarily. So, you just have to discipline yourself to wipe the slate clean as you go along.

I'm quite good at switching off and sometimes I forget who I am in a character.

I've traveled everywhere, and it's been amazing. I used to think taking a flight was kind of a big deal, you know? I'm from the valleys of South Wales and when my family used to go on holiday, it was a big thing. Packing the bags, checking in, not losing your passport, going through customs, the X-ray machine, all that stuff used to be quite an intense thing. Now it's like catching a bus, I don't even think about it.

I'll tell you a little fun fact about the film, though. Me, the little boy playing Chip, Emma Thompson, and Emma Watson, all have the same birthday. We were all in on the same day and they all sang us "Happy Birthday." That will never happen in my life again: Four of us having the same birthday on the same film, and we're all in on the same day. It was an extraordinary thing.

I felt alive when I read a script and acted out a scene, or sang a song. It was my dream. I'm just very lucky that I'm still doing it and able to earn a living from it.

I probably wanted to be a shopkeeper, because I like tills.
