TW: I think it's quite interesting to say that, looking at something that isn't 2D or the work of the Pre-Raphaelites and you don't really know the 3D-ness of it and I think that that's the adventure of making film. It's like walking into the woods, you don't really know what's in there. You take your inspiration from that painting there and you don't really know what it's gonna be and I think that's gone into making the mermaid film. We didn't know how it was gonna look as a 3D world. That last scene we did with Ben when he was drowning in the tank, it was so rushed and panicked, could he hold his breath? You go into that 3D world, not really knowing if it's gonna work, I think that's the joy and the fun and the danger of making a film.
The film is about an obsessive character. Can you relate to that in any way?
TW: I went to see Annie Leibovitz receive an award and they made a film about her and her life. They filmed one line, moving across her work and there was John Lennon and Yoko Ono, and then there was Obama and all these famous people. Then the camera went back down again and there's another line (of photos) and I thought that's just such an extraordinary life. The camera carried on moving and then it went down to another line and another line and it's just like I was thinking to myself at that point, this lady is so obsessive to the point where it's peculiar, taking all those photographs, but then I thought, hold on a minute, I'm a photographer as well! I think I'm just as obsessive and I think in a way, to succeed as a photographer, you have to be obsessive to the point of it being unhealthy.
And Ben, is there an element of obsessiveness in one's art that you can relate to? That you see manifested in a character? Does it exist in you? Do you ever go to extremes with what you're doing?
BW: Umm, I don't know. I can't really relate to it in the same way that Tim has just described. No, to be honest.
With your work, do you have a set formula of considerations for accepting or declining a role?
BW: No, I feel very open. The more unexpected, the better I do. I'm more drawn to things that I feel like I can't do or won't be very good at. So no, I don't have a criteria. It's an instinctive thing.
