It is said that truly potent scenes become the highlight of the whole movie. However, sometimes, some of the most unforgettable scenes in Hollywood history were completely ad-libbed. It's called unscripted performances.
Actors are just normal people. Given a script full of lines, sometimes, they forget their lines and then decide to create new ones. It turns out that these improvised scenes are better than the scripted ones and directors choose to go with them.
These moments easily stick in the minds of the audience, often becoming synonymous with the movie as a whole. The genuine reactions serve as reminders of the unparalleled influence of serendipity in the creation of even the most artfully constructed films.
