Stephen (on "Twilight" vampire, Edward Cullen): He's the Slim-Fast, Diet Coke of vampires.
Stephen (on the TruBlood drink in the show "True Blood"): It's like V8, but they put like 1,000 raspberries in a sieve, and they crush them and blend them. So it tastes pretty darn good, and it leaves a really great stain on your lips.
Stephen (on the success of "True Blood"): Honestly, I wasn't really surprised by the show's success, because I knew Alan [Ball] was creating the kind of stuff I'd personally be interested in watching.
Stephen (on his Southern accent in "True Blood"): I hadn't done a Southern accent since I pretended to be a cowboy when I was 7. I hadn't practiced at home, because I'd literally gotten the script the night before, but when I opened my mouth when we were doing the take, it was just kind of there.
Stephen (on staying pale for "True Blood"): I live by the beach, so I had to wear long sleeves and a floppy hat or I'd look like a Red Lobster ad.
Bill (on his relationship with Sookie in "True Blood") It's a sentimental, old-world kind of courting. [...] It's about being courted by someone who could rip your arteries out.
Stephen (on playing Bill in "True Blood"): I can't imagine being happier than I am at this exact second. I'm really proud of the gig. [...] It's a wonderfully calming position to be in. I feel very honored.
Stephen (on growing up in Essex County, England, during the Thatcher era): I was a bit of a geezer - a naughty, not very clever, bad boy. We all were.
Stephen: The thing I'll always carry from Quills was watching the Cricket Test Series with Michael Caine with plates of food on our knees. He had a satellite dish on the roof of his Winnebago. I was very happy, I have to say.
Stephen: I think New Yorkers and Londoners try to find comparisons with each other but they are very different. To New Yorkers, their city has a heart - it's a living breathing entity - and I don't think we think like that about London.
Stephen: (on acting in violent scenes with his character, Jimmy, in "Empathy") I'm not like that in real life, so when I get the chance to punch a bit of air and let out a bit of steam, I love it.
Stephen: The big difficulty with transatlantic relationships is that you want them to work and your whole heart is invested in it but it's the logistics that make it tough to keep it going. If you are an old romantic then it's really tough when things like logic take over.
Stephen: (in a 2007 interview) I said to my son not that long ago, 'What do you want to do when you're older?' He said, 'I'm going to have to go away and think about it.' So off he went. He came back and said, 'Daddy, I've decided that I want to be an actor.'
Stephen: (in a 2007 interview) If you'd asked me if I believed in the paranormal this time last year I'd have said no. I used to be an atheist, but I've chilled out a bit on that. A couple of things in the past year have made me think maybe there is something to it.
Stephen: ("we" being British actors) American actors are incredibly professional when preparing for a shot or getting into character, whereas we tend to be having a laugh and mucking about. We'll be more relaxed up until the point the camera rolls. That's not a criticism by any means, but there's a different way of working.
Stephen: (on working with director Jon Avnet) I love working with him. When somebody comes to the party with as much energy and as much enthusiasm as he does... he shoots everything as if it's The Godfather.
Stephen: I love the fact you can walk down a street in London and get lost even though you've lived here 20 years.
Stephen: (on shooting in New York) It was a dream to shoot there and not be a tourist.
Stephen: (on his "Ny-Lon" character, Michael Antonioni) He's this Essex boy who works in the city - I was drawn to this character who is not me at all but isn't a million miles from what I could have been.
