Ewan McGregor's nude scenes were originally going to be cut from the U.S. release, but after McGregor objected, the full-frontal nude scenes were put back in.
This was the first film which Mcgregor did not take his family along for the shoot.
There's a sequence in this movie in which Ewan McGregor empties a large bowl of custard on the half-naked Emily Mortimer, beats her with a stick, squirts ketchup and chocolate sauce on her, sprinkles her with powder and then has rough sex with her.
"There's something really liberating about letting it rip and just going for it," Mortimer says. "There's no way in real life you'll ever be allowed to get up to all that - I mean, unless you were really into kinky stuff."
After finding the body, Joe is sitting on a bucket at the dockside, a famous pose of that Dundonian cartoon rascal Oor Wullie, whose own father used to work on the docks.
