Mos Def and Martin Freeman in The Hitchhiker's Guide to the GalaxyTHE HITCHHIKER'S GUIDE TO THE GALAXY

The Hitchhiker's Guide to the Galaxy is something unusual: a movie wherein everyone involved appears to be having a good time. Of course, you could say the same about Cannonball Run or Ocean's Twelve, but the difference here is that the audience is allowed to have a good time, too. Based on Douglas Adams' cheeky, beloved sci-fi novel, Hitchhiker's Guide, which has been in various stages of film development for the better part of two decades, is a goofy, oftentimes glorious mess of a movie. If George Lucas and the Monty Python troupe ever spawned, the results would look something like this; I started smiling during the film's opening credits and only stopped to occasionally laugh out loud.

Al Pacino and Rachel Roberts in SimoneSIMONE

Andrew Niccol appears to be obsessed with a theme that, in all likelihood, he can spend his entire filmmaking career exploring: What is the nature of reality? In 1997's vastly underrated Gattaca, which Niccol wrote and directed, he investigated the perils of genetic engineering, as his biologically "natural" protagonist Vincent assumed the identity of the genetically "perfect" Jerome to further his space-exploration career; the film, which on paper might seem a cerebral sci-fi comedy of mistaken identity, dramatized what it meant to be "real" in an unreal world, and was a heady, thrilling experience.
