The film is quite a precise dissection of a relationship gone bad. Is there a lot of your own personal trauma in there?
"Yes, but it all came from Scott Neustadter, who's the writer. It's really his experiences, he wrote it with Michael Weber and then we developed it for a while. There's some of my personal vignettes in there. When we first met we all sat around and went through our relationship war stories and we had a lot of common reference points. It was surprising to see young men react to the film. It emanated from something autobiographical but not so much from me."
Does that mean Jenny Beckman is real?
"Whatever you do don't Facebook Jenny Beckman. Don't friend her on Facebook! I can't get too deep into the Jenny Beckman thing. Suffice to say it is based on real experience, we had to get the okay from certain people in our past!"
How did you come to cast Joseph and Zooey?
"We cast Zooey first actually, but I met Joe before I met Zooey. We were talking about who could play Summer and Joe talked about the obvious names and then he said, 'Really, the person who should play this is Zooey.' After he said that he deflated and said, 'No-one is ever going to make a movie with us because we're not big enough stars.' I just remembered that and then when I met Zooey the studio was saying if she'll do it we've got something. Luckily she signed on and I had the leverage to bring Joe on. They knew each other and they had a familiarity and mutual respect which I felt was really important."
Did you get all the songs you were after for the soundtrack? In the karaoke scene Summer says she wants to sing 'Born To Run' but it isn't on the jukebox.
"That was. That was in there, we were going to do 'Born To Run', which is one of the great American street operas. We all love The Boss. Scott's from New Jersey where Bruce Springsteen is from. That was one song we couldn't get, the other we couldn't get was the music from Le mépris, the Jean-Luc Godard movie. We used that during the foreign film sequence which worked really, really well. Very melodramatic. Other than that we got pretty much everything we wanted to use. There was a lot of letter writing and a lot of personal appeals."
Will we see (500) Days Of Autumn?
"I don't know, maybe! I'll have to talk to Minka [Kelly] about that!"
(500) Days Of Summer is in cinemas now.
