By way of Quiddity, the cast of Hitchhiker’s Guide gets rounded out, and I like what I’m hearing. According to the Hollywood Reporter, Mos Def will be Ford Prefect (good race-neutral casting, although I hope he’s still British), Zooey Deschanel plays Trillian (how’d her agent ever manage to stop the Knightley Behemoth? Keira’s got more momentum these days than Kerry) and Sam Rockwell is Zaphod Beeblebrox, president of the universe (That’s classic…but no word yet on how or if they’re casting his second head.) This should be fun.
