Fahrenheit 451 is a 1966 science fiction film directed by Francois Truffaut and starring Julie Christie. It's based on the book by Ray Bradbury.
The Cinemated Man offers the film on Blip.TV:
The film itself starts about 5 1/2 minutes into the video.
Moria has a review, giving the film 4 stars. 1000 Misspent Hours says, "Unfortunately, a lot more went wrong with Fahrenheit 451 than went right, and a lot of what went wrong is absolutely inexplicable." The New York Times calls it "pretentious and pedantic" and "dull" and "bloodless and pompous". Variety says it's "thoughtfully directed". Senses of Cinema has an article.
