"Dickheads." That's what die-hard fans of prolific science-fiction author Philip K. Dick call themselves. And that is certainly the attitude adopted when Dickian canon is messed with.

This weekend marks the release of the latest PKD adaptation, 'The Adjustment Bureau,' starring Matt Damon. In the film, Damon stars as David Norris, a young, charismatic politician who discovers his life plan is controlled by a mysterious, otherworldly organization known as (you guessed it) the Adjustment Bureau. 'Bureau' is based on Dick's story 'Adjustment Team,' but only loosely based. The jury is still out on whether this new movie will please or anger the Dickheads.

As far as straight-up PKD film adaptations go, the pool is a pretty shallow one to choose from. But, still waters run deep, and we are fortunate enough to have some true masterpieces in the running. We also have a wealth of untapped source material to choose from for future adaptations. Without further ado, Moviefone presents the five best PKD film adaptations and five more that we'd love to see happen (including our picks for who should make them).
