"Have you ever noticed two movies that seem the same? Maybe you're not even sure which is which or if you've seen one or the other.
Hollywood has a long history of competition, which sometimes means producing a movie to outdo a rival studio. For that reason, Stacker compiled a list of 10 occasions in which two movies that told the same, or an eerily similar, story came out in the same year. More than a few films on our list went into production to capitalize on or compete with another movie's influence.
That said, even films with a remarkably similar premise, like animated ant colonies or aerial dogfights, turn out completely different by the time they're in theaters. A few movies on our list, like "Top Gun" and "Zero Dark Thirty," are way more popular and acclaimed than the films they resemble that premiered the same year."
