The whole first movie [Twilight] was pretty fun. I had never really done a movie like it, when there's such a big cast of people that are around about the same age. Everyone didn't really know what was going to happen with the movie, but there was a good energy. There was something which people were fighting for, in a way. They wanted it to be something special. None of us were really known then, as well. It felt like a big deal, at the time.

I still had the same frustration with trying to play [Edward Cullen], the entire way through, right up until the last shot. It's a strange part because, on the one hand, a lot of the audience projects their idea of Edward[Cullen] onto him. It doesn't matter what he is. They want him to be a certain way. And then, my instincts were to try and play it and to try to find the fallibility in him and the weaknesses.

I aspire to be Jack Nicholson. I love his every single mannerism. I used to try and be him in virtually everything I did, I don't know why. I watched One Flew Over the Cuckoo's Nest when I was about 13, and I dressed like him. I tried to do his accent. I did everything like him. I think it kind of stuck with me.

My worst habit is speaking to much

It was hilarious [last scene with Edward Cullen] considering we'd spent the entire series filming in the most miserable conditions, and then we end on the beach in the Caribbean filming for two days in the sea. That was fun. We literally did the last shot as the sun was coming up in St. Thomas in the Virgin Islands. It was a nice way to end it, because they were considering shooting it in the sea in Vancouver, which would not have worked at all.

What worries me the most is that I don't know when my patience will run out, when I'll finally do something really stupid. Wait and see.

The special effects team designed everything, which basically allowed me to stand on a green box and look and stay relatively expressionless and all these machines did the acting for me. Just the way I like it (laughs)
