"Jason Bateman was the first person I cast in the movie. I didn't know him, I met him on someone else's recommendation, and he didn't want to do any of the big parts, the part that really leapt out at him was this character who's only on something like 15 pages of the script. I cast him there and then. He's great because he's comedic but he's also rather unpleasant as a character. At the end, when he cries, you realise he's actually a rather pathetic individual -- all front which is cruelly exposed. It's a great moment in the movie, because after the twists and turns of the plot you get a 15-minute relief with him. It's a hard balance to get right in the cutting room, trying to get the comedic elements to mix with the thrills and the twists."
