Don’t you hate it when you don’t get around to seeing the hot new Hollywood movie for a couple of weeks…and then a friend lets slip how it ends? It’s very aggravating. It’s perplexing then that some movies gave away their endings before they were even released.

ROCKY IV

Rocky IV is yet another Sylvester Stallone boxing drama starring the “Italian Stallion,” but set against the backdrop of the Cold War, and its decades-long tensions between the U.S. and the Soviet Union. In the movie, good old fashioned American Rocky Balboa goes up against the almost robotic Soviet super-boxer Ivan Drago. Who wins? Well, you can tell from the poster used to promote Rocky IV. It depicts Stallone triumphant at the end of a fight…wrapped up in an American flag.

GREASE

Grease is one of the most successful movies of all time, probably because of songs like “Summer Nights,” the nostalgic 1950 setting, and the star power of John Travolta and Olivia Newton-John as the leads. They play Danny and Sandy, respectively, two very different teenagers who finally fall in love despite the many obstacles placed in their way throughout the school year. Mostly their different stations in life keep them apart—Sandy is a conservatively dressed “good girl” (her friends derisively compare her to Doris Day and Sandra Dee), while Danny is a hot rod-racing greaser. Ultimately, they change for each other—Danny takes up track to be more mainstream, and Sandy shows up at the end of the mother dressed in a provocative leather outfit, and smoking a cigarette. It’s a shocking twist—and Olivia Newton-John was depicted in all of the promotional materials for Grease in that leather outfit.

THE PHANTOM MENACE

Despite notoriously underwhelming audiences, the first Star Wars prequel, The Phantom Menace, had a lot going for it—such as popular actor Liam Neeson in a leading role, playing a new Star Wars character, a mysterious Jedi named Qui-Gon Jinn. But prior to the film’s hugely anticipated release in May 1999 however, the movie’s orchestral soundtrack (composed by John Williams) hit music stores. One of the score tracks on the album: “Qui-Gon’s Funeral.” Spoiler alert: Qui-Gon dies in the The Phantom Menace.

SPEED

The 1994 action movie had a simple but compelling premise: If a Los Angeles city bus drops its speed under 50 miles per hour, a terrorist-planted bomb will explode. It’s up to a cop (Keanu Reeves) and a normal woman who takes over driving duties (Sandra Bullock) to save the bus, and everyone on it. Speed has a happy ending, with the passengers on board surviving the ordeal, despite the bus blowing up at one point. However, that explosion—and the passengers reacting to it, after their escape to safety—is all right there in the Speed trailer.
