Movies are an incredibly huge undertaking. It takes a village (or an army, depending on who you ask) to get a film made. They say you make a film three times: once in pre-production, again while you're filming, and finally while your editing. At any of these points lightning can strike and completely change the course of the film.
This is a collection of famous, unscripted dialogue in classic films. Those one-in-a-million pieces of magic where an improvised line struck all the right chords and became legendary. These are the most famous film lines that were unscripted!
In this scene, there was no specific dialogue. The script merely said, “Travis talks to himself in the mirror." Every single thing that Travis Bickle (Robert De Niro) says during his insane conversation with himself in the mirror was improvised by De Niro on the spot.

All the script called for was Luther (David Patrick Kelly), leader of the vicious New York gang, the Rogues, to drive up and provoke the Warriors to a fight in the streets by clinking bottles together.
Kelly then ad-libbed the most famous line in the film, "Warriors, come out to play!"

This entire scene was apparently made up as they went along. What makes it especially wonderful is that, Mike Starr, the actor getting his ears screamed into, can't tolerate loud noises in real life. So, not only are Jim Carrey and Jeff Daniels's lines and obnoxiousness all improvised, but Starr's reactions to them are completely genuine, as well.

While luring the great white shark within range, Police Chief Brody (Roy Scheider) gets his first look at the shark and how impossibly large it is.
Stunned, he stands and mutters the now famous line to Captain Quint (Robert Shaw) completely off-the-cuff, “You’re going to need a bigger boat.”
