Less than 40 theaters agreed to book showings of Star Wars after its release date was moved up to before Memorial Day (the studio thought it would bomb in a crowded summer movie slate). Around the same time, 20th Century Fox was going to release an eagerly anticipated adaptation of a bestselling book called The Other Side of Midnight, which theaters were eager to show. Fox then stipulated that any theater showing The Other Side of Midnight must also show Star Wars, which inflated the number of screens for the movie.
Needless to say, Star Wars eventually became the highest-grossing movie ever made up to that time, while The Other Side of Midnight didn’t even break the $25 million mark. And as requiring movie theaters to show one movie in exchange for another movie was actually illegal, 20th Century Fox ended up being fined $25,000—for forcing theaters to show The Other Side of Midnight.
