I feel I should add my personal collection to this. In no particular order:
I Robot
Will Smith tries to warn a scientist (who's name escapes me) that the robots are evil. After they revolt humanity, Smith bursts into the scientists house, machine guns her personal android to death and says...
"Y'know, somehow, "I told you so" just doesn't say it."
Scott Pilgrim vs the world
In the middle of a fight between Scott and Todd...
Scott: I dislike you, capishe?
Todd: Tell it to the cleaning lady on Monday.
Scott: What?
Todd: Because you'll be dust by Monday.
Scott: Uhm?
Todd: Because you'll be pulverized in 2 seconds. And the cleaning lady, she cleans up dust. She dusts.
The Dark Night
Alfred and Bruce discussing Bruce handing himself in...
Bruce: Today's the day you get to say "I told you so".
Alfred: And today, sir, I don't want to.
[Pause]
Alfred: But I did bloody tell you.
Ghostbusters
After an explosion at the Ghostbuster's facility, The Ghostbusters and Walter Peck (and environmentalist who caused the explosion) talk to the mayor...
Raymond: Everything was fine with our machines until the power grid was switched off by dickless over here [indicates to Peck].
Peck: They caused an explosion!
Mayor: Is this true?
Peter: Yes it's true. This man has no dick.
Now You See Me
Merritt and Henley on a plane discussing Henley's love life...
Henley: Wow, thanks. Let me mull over that offer of cheap and meaningless sex.
Merritt: Cheap and meaningless, maybe, but, uh, not time-consuming.
