Monty Python meets Wars aving ready spawned a cult as a series of books, radio shows and a 1981 TV series, Hitchhiker finally thumbs a hot ride to the big reen. The mission impossible, which first-time director Garth nnings has bravely accepted, is to hold true to the droll, gressive, very British verbal humor of the creator Douglas Adams e died in 2001) in a movie that spills over with visual gags, ppet monsters and a digital John Malkovich. Even when the PG lm plays it safe, the script by Karey Kirkpatrick and Adams mself delivers the goods in inspired lunacy. Plot? Arthur Dent, e Brit Everyman perfectly played by Martin Freeman (The Office), kes up to find bulldozers ready to raze his home. Before he can op them, his pal Ford Prefect (a lively Mos Def) tells him not bother, since Earth is about to be destroyed by an alien race Vogons, and reveals that he, too, is an alien, whose book — The Hitchhiker's Guide to the Galaxy — is a big seller in hyperspace. rd and Arthur stow away on a ship manned by Zaphod Beeblebrox, ayed by Sam Rockwell with a mad glint befitting a galaxy esident with two heads, three arms and an earthling passenger dorable Zooey Deschanel), whom Arthur once hit on at a party. n't panic, you noncultists. Go with the whimsical flow that cludes a hilariously morose robot named Marvin, voiced by the eat Alan Rickman with the weight of the galaxy resonating in ery bored, cynical syllable. Adams would be pleased.
