The 32 Greatest Unscripted Movie Scenes

The Godfather (1972)Director - Francis Ford Coppola Vito Corleone (Marlon Brando) is more than the cold-hearted head of a powerful Italian mob family. That trait shows when he sentences a man to be beaten as retaliation for the beating of another man's daughter - all while gently stroking a cat. Thing is, the cat was never part of the original script. Some reports say that Coppola plopped the feline into Brando's lap just before filming began. Other reports say Brando found "il gatto" roaming around the set, picked him and gave him an offer he couldn't refuse (heh).

Dumb and Dumber (1994)Director - Farrelly Brothers There are many scenes in the film that show how moronic and simple-minded best friends Lloyd Christmas (Jim Carrey) and Harry Dunne (Jeff Daniels) can be but this one showed how annoying they can be on car trips - and it was entirely unscripted. Even hitman Joe Mentalino's (Mike Starr) hissy fit reaction to the scene was unscripted, which makes the scene that much funnier.

Jaws (1975)Director - Steven Spielberg While chumming the waters in an attempt to lure the deadly great white shark within range, Police Chief Brody (Roy Scheider) gets his first look at exactly how massive the killer shark truly is. Stunned, startled and filled with fear he stands up and utters the now famous line to Orca Captain Quint (Robert Shaw) completely off-script, "You're going to need a bigger boat.” Turns out, he was right.
