The Hitchhiker's Guide To The Galaxy: According to The Hollywood Reporter, Sam Rockwell should have a lot of face time in Spyglass Entertainment/Walt Disney Co.'s "The Hitchhiker's Guide to the Galaxy" -- a big-screen adaptation of the cult hit novel by Douglas Adams -- because he'll be playing Zaphod, the two-headed president of the galaxy.

"Galaxy" begins shooting in April in London with Garth Jennings at the helm. Mos Def, Zooey Deschanel and Martin Freeman also star.

Mos Def plays Ford Prefect, an alien disguising himself as an out-of-work actor who sets out on an intergalactic journey with his best friend, mild-mannered earthling Arthur Dent (Freeman). The duo hitch a ride through space with Rockwell's Zaphod, the beautiful and brilliant scientist Trillion (Deschanel) and a depressed robot while on a quest to discover the meaning of life.
