So what is this reflective darkness in Bourne's soul? Is it gay-man melancholy? Has his life perhaps been defined by loss? Not at all. 'Only in recent times, when my mum died during the making of Edward Scissorhands,' he offers. 'I was always very happy actually. My life has been an extremely happy one. I didn't even struggle to come out that much. I was out happily at 18, in a very uncomplicated way, as soon as I realised I was gay.' Stir in his loving relationship (Arthur Pita, 12 years his junior, was a swan when they met 12 years ago), his two adorable dogs, his professional triumphs, and you've got to wonder why this is the man who doesn't like happy endings, who even fiddled with Edward Scissorhands to darken the original's finale. No redemption here. But why? 'I just don't know. I search to find what that thing is,' Bourne muses. 'I do like to feel something for the characters, so I feel I need to put them in situations where they are suffering in some way so they can win through. That's the arc of a good story. The more you make the character really happy here, then bring them down there, the more we as an audience will feel it. It's about the highs and the lows.'
