There's a loooooooota good shit in the last 20 years.
Ferrell really did provide just a flurry of quotable shit in the 2000s-"You're my boy, Blue!", etc.-that I would say have aged better and are less annoying then when everyone was quoting Jim Carrey in replacement of a personality in the 90s.
Most of mine are not in the poll. For example, "You had my curiosity. Now you have my Attention." Only issue with that Django Unchained quote is it might work better as a meme than a quote.
Also, although I dont love the movie, The Departed does have an all-timer-"I'm the guy that does his job. You must be the other guy."
So insane that "I AM THE CAPTAIN NOW" from Captain Phillips was adlibbed. One of those great Hollywood stories.
I love when Maximus reveals his identity in Gladiator. Hard to use in normal conversation though.
(My name is Maximus Decimus Meridius, commander of the Armies of the North, General of the Felix Legions and loyal servant to the TRUE emperor, Marcus Aurelius. Father to a murdered son, husband to a murdered wife. And I will have my vengeance, in this life or the next.)
