Apparantly, Ray Bradbury isn't best pleased with Michael Moore for using 'his' title for the movie. I would've thought he'd be flattered by the place Farenheit 451 has in the popular vocabulary that Moore COULD call his movie that, especially since it covers the same grounds as Bradbury's work (restrictions of freedom and the enforced ignorence of a population by a right-wing government).
Mind you, if you've ever read any interviews with Ray Bradbury, it doesn't seem THAT surprising.
BITTER much, Mr Bradbury?
