The offbeat British comedy "Absolutely Anything" promises to be a remarkable viewing experience, and not just because it's already managed to wrangle the Monty Python gang in a voice-over reunion. There's also a bittersweet reason: It will star Robin Williams in his final on-screen role as the voice of Dennis, an unusually hyper dog.
The film is being classified as a "science fiction comedy" and follows a disillusioned school teacher (Simon Pegg) who is granted omnipotence by a group of aliens (voiced by the Monty Python crew).
"Absolutely Anything" will be released August 14, almost exactly a year from the date of the actor-comedian's death. It will be one of two Williams projects rolling out this year posthumously -- the other, a drama "Boulevard," slated for a July release.
