The Hitchhiker's Guide to the Galaxy: According to a recent interview on BBC Radio 1, Alan Rickman and Bill Bailey have apparently joined the cast of The Hitchhiker's Guide to the Galaxy...

Garth Jennings has just confirmed two amazing bits of casting in a mini-interview on BBC Radio 1. The voice of Marvin will be Alan Rickman and Bill Bailey will play the whale!

Alan Rickman is a highly regarded actor whose notable recent movies have included Dogma (directed by Hitchhiker's Guide fan Kevin Smith), Galaxy Quest (alongside Sam Rockwell) and the Harry Potter films.

Garth did say that Rickman's contract wasn't signed yet but this interview was almost certainly taped befire Christmas and it would not have gone out if Rickman wasn't locked down for the role.
