25 Unscripted Movie Moments that Made the Cut

It might be surprising to hear that some of the most iconic lines from movies weren’t originally a part of the script.

A screenwriter could spend months, even years, developing a story. However, if the director allows an actor to ad-lib, he or she has the power to create completely new lines right on the spot.

Creative ad-libbing takes some serious skills and not any actor can pull it off. 

If you are curious to find out which of your favorite movie stars are impressive improvisers, look no further. In this article, you will discover the top 25 Unscripted Movie Moments that Made the Cut!

This is Spinal Tap


Improvising is quite difficult and doesn’t always work. However, the spoof rockumentary This is Spinal Tap showed that it was possible to create a movie almost completely from ad-libbing.

The film stars Christopher Guest, Michael McKean, Harry Shearer, and Rob Reiner. These actors were all given credit for the movie’s screenplay since they improvised most of the script.


I Don’t Care!


The 1993 crime-thriller The Fugitive stars Harrison Ford, Tommy Lee Jones, and Sela Ward.

The story revolves around a wrongfully accused man, Richard Kimble, trying to find his wife’s true murder.

One of the most telling scenes was made even more memorable by Tommy Lee Jones forgetting his lines. Instead of saying, “That isn’t my problem,” he blurts out, “I don’t care!”  


Son of a B*tch, He Stole My Line!


The late Robin Williams was considered to be a comedic genius. He poured his soul into every role he played.

It comes as no surprise that one of the most beloved lines in Good Will Hunting was created by him on the whim. Co-star Matt Damon later told Boston Magazine that Williams came up with a different line during each take of the final scene.

However, when he delivered, “Son of a b*itch, he stole my line!” Damon recalls it as an electric moment.


My name is Forrest Gump. People call me Forrest Gump


The 1994 drama-comedy Forrest Gump is considered to be a movie masterpiece. It went on to win six Academy Awards and receive three nominations from the MTV Movie Awards.

Director Robert Zemeckis admits that a few of the most iconic lines were a product of Hanks’ ad-libbing. One of the favorites is, of course, “My name is Forrest Gump. People call me Forrest Gump.” 



Gimmie a Break!


You might be surprised to hear that famous actress Drew Barrymore began her acting career at just 11 months old.

So, by the time she joined the cast of E.T. The Extraterrestrial, she had six years of acting under her belt.

A few of her ad-libbed lines even made it into the movie. A few of them were in the unforgettably adorable, “Gimmie a break!” scene.
