Another list...

The Independent has a list of the best movie quotes. I don't agree with all of their choices, and will defend to the death some they list as clunkers, but they have some great categories, and they are indisputably right about this:

There are two monologues in cinema history that tower over all others, and you know what they are. That's right: Brando's despairing "I coulda been a contender, I could been somebody," speech as Terry Malloy in On the Waterfront (1954); and Orson Welles' "cuckoo clock" speech in diabolical justification of his crimes as Harry Lime in The Third Man (1949).

And these may be clunkers, but they are fun:

How about Andie McDowell as Carrie, resembling nothing so much as a drowned rat, to the sodden Hugh Grant in the downpour that marks the end of Four Weddings and a Funeral (1993): "Is it raining? I hadn't noticed." Or Sean Connery in Goldfinger (1964), cracking a crime ring and keeping straight-faced long enough to deliver the line: "At least they won't be using heroin-flavoured bananas to finance revolutions."

You could fill a phone book with atrocious lines from sci-fi and horror movies, but we'll content ourselves with two examples. Here's Roddy Piper in John Carpenter's They Live (1988) as Nada: "I have come here to chew bubblegum and kick ass. And I'm all out of bubblegum." And, from Flash Gordon (1986): "I love you, Flash, but we only have 14 hours to save the Earth."
