10 Movies That Changed Their Premise Halfway Through (& Got Better)

While consistency is key to success in any art form, some movies threw out the rule book and improved by abandoning their original premise entirely. A great concept is often enough to sell audiences on a movie. When Alien was originally pitched as “Jaws… in space,” the filmmakers already knew they had a potential hit on their hands thanks to that logline alone. Even before a director has been hired, or any characters have been cast, a brilliant premise is sometimes sufficient to get viewers invested in a movie. This makes it a surprise when movies throw away one plot in favor of another.
