It shows the kind of man he is. To allow any emotion would be unseemly for him,

Daniel had to put up with a lot from me. Here's a boy who's tied up with a man pushing his finger into the wound on his head, laughing and delighting in the pain he's causing. He had to act as though he was in agony and terror without having many words to say. I was full of admiration for him.

Justin's journey traces not only what Tessa was investigating; he's also playing detective about their relationship. This man rediscovers and re-assesses his own relationship with his wife. It's a wonderful part, because he goes from being a reticent nice guy to being someone who is forced to confront some pretty tough truths about the world. I hope that the audience sees him as a kind of 'everyman.'

It was just two energies between two people, you can't prescribe that.

You dread that there will be real problems during filming.

I like to keep fit, but I never lift very heavy weights.
