(on frequently appearing masked on screen)
Warwick: To me that's part of my working day, and I would never refuse a job where I'm under several hours of makeup, because as an actor, I enjoy performing. It's about the creation of the character and the art to me, not about being comfortable and how long it all takes. Nothing's better than coming away from a film when people don't even recognize you, because you've undergone a total transformation.
(on looking on the internet about himself)
Warwick: I think it's fun to go for a little surf and see what's out there. It's interesting to see what people are saying about me. I like keep up with the latest rumors! A while back there was a rumor that I was going to do a film with Demi Moore about the take-over of Commodore computers!
(on whether or not he is amazed by the continuing interest in the original Star Wars films.)
Warwick: Yes and No. I'm amazed I'm still talking about it 25 years on, that there's still a huge amount of interest in these films, but I'm not amazed because the ideas, and the way that George made the films, are timeless. The simplicity of them is astounding in a way, because the basic story of Star Wars is very, very simple – it's good versus evil. You've got fairly straightforward characters, and characters I think people can identify with. At the same time it was very well executed – the way it was put up on screen was just perfect – and that world of Star Wars is as detailed as our world.
(on how people think of him)
Warwick: [people think I'm] Not as ordinary as I think I am. They don't approach me as much as I would like, because they think I'm too successful. But I'm still just me. I take the rubbish out and everything!
Warwick: I would definitely greenlight a Willow sequel. So many people ask me about that. Every day people want to see another movie. I'd be very excited for it, because I was 17 when I did that movie and to go back and have another chance at the character now. I've learned so much more, it'd be great.
(on appearing in "Extras", with Ricky Gervais)
Warwick: Actually, it's really quite surreal because I was referred to as Warwick while on set, but I wasn't really portraying myself. That is one of the really fun elements of Extras. Ricky reveals the unexpected from people that you think you know. The public have one perception of an actor and Ricky turns that on its head in Extras so that you're playing a wholly different version of yourself.
(about his dwarfism)
Warwick: As you get older, you can suffer from painful hips, and our joints wear a lot quicker than for people of average height.
