Because the first one went too long.
Here's how this will work: one person drops a movie quote, bereft of context, and everyone tries to guess/remember which movie it's from. We keep it going from there.
When offering up quotes, try not to make them too easy (No "Frankly, my dear, I don't give a damn" or "Do or do not, there is no try" type quotes), but also don't go for incredibly obscure quotes that no one's ever going to know because it's from a 1909 movie of which only two extant copies survive and you own one of them.
If no one can guess your quote, feel free to drop hints.
Also as a reminder, don't look up the quotes.
