Movie Details About Improvised Moments That Demand A Rewatch

List Rules
Vote up the details you missed the first time around.

Movies are the result of thousands of hours of work by hundreds of people (if not more), and they all follow a carefully written, edited, and rewritten script from start to finish. Actually, that's how it's supposed to work. In reality, scripts go through multiple rewrites by several people, and the actors often weigh in a lot as well, which can lead to some of a movie's greatest moments consisting of unscripted lines. Improvisation can often add clarity or levity to a scene, and when it works, it feels natural, leaving many to assume those lines and moments were always meant to be included.

Because of this, few people realize that their favorite moments from beloved movies stem from one or more people's improv. When fans notice one of these movie moments, they occasionally head over to the MovieDetails subreddit to share their findings. This list takes the very best examples of improvised movie moments that are so well done they demand a rewatch.

    From Redditor u/Russian_Bagel:

    In The Dark Knight (2008), Joker is constantly licking his lips. This is actually because of the prosthetic scars that Heath Ledger wore. They kept falling off, so Heath would lick his lips to keep them in place. Gradually, it became a part of the Joker’s character.
