I've been robbed!

Rating: Null/10 (29 October 2004)

Just sat through the DVD of 2001: A Space Odyssey, which I have not seen for years, and i'm waiting for the immortal line from Dave as he floats over the
Jupiter monolith "Oh my God. Its full of stars" and to my horror the line is not there. He never says it! So I check the film by fast forwarding back and forth to see if I have dropped off and missed it but no, its not there. So I check with a few 2001 buffs on the net and they all talk about "the immortal line". So I have not imagined it or got confussed with another movie.
Seems I have bought an edited version of the movie that doesn't have that line in it! How come? Why edit it out? And more importantly how do you know when
you are buying a DVD that some bastard censor has deemed a line too strong
for a U cert? Answers if you have them would be welcomed.
