How was the Twilight experience changed you?
RP: I’m probably more insecure. My ego got smaller [laughs]. I thought I was pretty cool after the first one. I finished the movie and for the first time, I had some money. The Twilight trailer had come out and got eight million hits so I had all the best parts of being in a big movie. I had meetings were people were saying, ‘This is the new hot thing, eh?’ Everyone gave a shit about you, but no-one knew who you were outside of that. So I spent eight months getting wasted with everyone thinking I was great. It was really fun. It was different at the start. TMZ and all that stuff was getting prevalent and now, it’s insane. Becoming big now, you became insanely conservative. Terrified about everything. Now I just stay at home.

Did you keep any mementoes from the films?
RP: The first one, I kept pretty much the whole wardrobe because I didn’t have any clothes then. There was an interview I did – with MTV or something – with a superfan. I was supposed to go in and surprise her, and after 10 seconds, she was like, ‘Are you wearing the same outfit as Edward?’ I’d completely forgotten, but they were the same clothes!

Kristen describes you as being ‘ridiculously ambitious’. Is that true?
RP: I think I want to be…The difference between me and Kristen is that she can do a day of work and at the end of the day be like,’I did the absolute best I could. Satisfied.’ Whereas I don’t think I’ve ever had that day in my life. I always go home irritated and want to fix it the next day. I don’t know who has the bigger ego in that case. Whether hers is bigger because she thinks what she did is fine, or whether mine’s bigger because I think I’m so great it’s never going to be good enough.

What has the franchise done for you career in general?
RP: It’s done a lot. But the same time, you have to steer it. You can sink just as quickly as someone who’s never had this. It’s not a free pass. I think about how to carefully plan the route afterwards. You can’t do anything you want. And if I ever stop acting, I want people to remember my stuff as interesting after I got given my break.
