Thumbs up to this cosmic comic joyride adapted from the Douglas Adams sci-fi cult adventures. Mos Def is a blast as alien planet-trotter Ford Prefect, and Martin Freeman is equally fun as earthling Arthur Dent, his traveling companion and best friend. Sam Rockwell costars as Ford's cousin, Zaphod Beeblebrox, a galactic president with three arms and two heads. The animatronic monsters were designed by Jim Henson's Creature Shop. Zooey Deschanel, John Malkovich, Bill Nighy, Anna Chancellor.
