Cillian Murphy: Hi.

Int: Can you tell us a bit about the role that you play in the film?

CM: Yeah, I play Capa who is a physicist, and that's his responsibility in the crew he looks after the bomb, the payload which we are going to attempt to shoot into the heart of the sun to keep it burning.

Int: Now the film looks into the future and predicts a world where the sun is dying. Did you have to do much research for this role?

CM: Yeah, I did a lot of … we all did a lot of research collectively, we did about a month's prep prior to shooting, you know we got a lot of lectures from scientists, we um, we went and experienced zero G, we went scuba diving. I went to CERN in Geneva and witnessed the building of this particle accelerator which is like 25 miles in circumference underneath um, it's between the border of France and Switzerland and hung out a lot with Brian Cox who is the science advisor on the film. Um, yeah there was a huge amount of research and that's Danny's idea that you absorb all of this so that you recognize the significance of what you're … of what the mission is about and … when you're playing the characters.

Int: This is a very psychological film so is that quite hard in terms of the acting style that you had to do?

CM: Ummmmmm, no I mean that is kind of the traditional science fiction set up you know there's a group of astronauts and they're on a … in a confined space and stuff goes wrong and it's how it affects them all psychologically so you just have to commit to it and give your hundred percent you know.

Int: And was the film's subject something that interested and intrigued you?

CM: I wasn't … I'm not a … I mean I didn't know much about science really prior to this, it's not something I would have been very good at in school but it was very revelatory, like talking to Brian Cox and reading the books about it and it has … I have kept my interest in it since.

Int: And are you a fan of space films?

CM: Um, some, the good ones, yeah. [laughs]

Int: And what about Danny Boyle, you've worked with him before, 28 Days Later…, was it good to be working with him again?

CM: Yeah, I mean Danny's an incredible director and he makes incredible films, very original, unusual films, you know I was a fan of his films way before I ever got to work with him and 28 Days Later… was really important for me as an actor and for my career so it was great to be back and you know I hope … I've gone away in the meantime and worked on different projects so I had more to bring to the table this time I think.

Int: And do you hope to be working with him again in the future?

CM: I'd love to, yeah. But it has to be the right role I suppose.

Int: And what sort of audience do you think Sunshine is going to attract. Who will it appeal to?

CM: Well I think that there's your obvious, you know… people who are into science fiction movies and who appreciate this sort of film. I think it will appeal to a wider audience as well, anyone who's interested in something visual and something intelligent, interested in something um thrilling. [smiles] Any of those things.

Int: You've worked with some big names previously in the acting world, was it good to work with a mainly young and up and coming cast in this film.

CM: Yeah, they're all wonderful actors you know and we had great fun working together and we all lived together prior to shooting the movie and that was great craic. So yeah, they're all brilliant actors.

Int: Is that something you would normally do?

CM: Live together?

Int: Yeah.

CM: [Smiling] No.

Int: Was that quite strange?

CM: No, it was great, I mean the idea was to sort of you know sort of recreate or create the idea of being on a ship and living in a confined space and having to be in each other's personal space all the time cos you know the first scene of the film we're all sitting around and the idea is that they've been sitting around and having dinner every night for the last sixteen months so you want to … to act that well it's a brilliant bonus to have actually lived it you know.

Int: So you got to know the other actors very well, I imagine.

CM: Yeah.

Int: Is there a major difference working on a smaller British film as opposed to some Hollywood films that you've been in before?

CM: No, I mean a film set is a film set really. Um I guess there is a different amount of excess that can be applied to certain types of films where as some sort of other films you know there's a … there's not a lot of money um but this one's kind of mid-budget and it was in London which was nice.

Int: So you've been nominated for a Golden Globe last year for your performance in Breakfast on Pluto. Is it important to be recognized in the U.S. for your work?

CM: It's nice. It's not why you make films. You make films cos you want to make something important and something that's entertaining and any of the recognition is not anything that you can control so it's nice when it happens.

Int: Are there any actors that you'd still like to work with?

CM: Loads.

Int: British or…?

CM: [Smiling] Loads. Yeah. But there's too many to mention, you know.

Int: And what effect do you think the Internet is having on the film industry at the moment?

CM: Well it's very important I think and I think film studios are recognizing how important the Internet is in terms of the build up of a film particularly and you know every film nowadays has a website and you can kind of judge I think by the Internet how big or small a film is going to be by the interest it's generating and you know websites like Ain't It Cool and websites similar to that are very, very important so I think it has a huge effect.

Int: I think it's been quite important for this film as well, the buildup.

CM: Yeah, I mean it appeals to that type of audience as well I think you know which is great, as did 28 Days Later… you know.

Int: Okay, thank very much for talking to Yahoo! Movies.

CM: Thank you.
