Star Wars: Return of the Jedi
Working title: Blue Harvest
By the time the third installment of the original Star Wars trilogy began production, the hype was high. George Lucas wanted to be able to work on the film without attracting swarms of curious fans or reporters who might spread spoilers. So he gave Episode VI an unexceptional working title: Blue Harvest. He even came up with a tagline for his fake movie to really throw people off: “Horror beyond imagination.” And there’s even a behind-the-scenes set photo of an Ewok holding a clapperboard labeled “Blue Harvest.” Secrecy at its finest.
Bonus: Blue Harvest actually wasn’t Return of the Jedi‘s only working title. The film was originally going to be called Revenge of the Jedi, until George Lucas decided that the concept of revenge didn’t suit the peaceful Jedi way. We bet you didn’t know these mind-blowing facts about Star Wars either.

Working title: Planet Ice
Considering the fate of the Titanic, this working title might seem a little too on the nose. While making the second highest-grossing movie of all time, James Cameron wanted to throw other film studios off of his trail. When he had to shoot a scene off the coast of Nova Scotia featuring lots of icebergs, keeping this, well, titanic secret became a bit more challenging. So he claimed that his project was a science fiction movie called Planet Ice. See if you can guess the highest-grossing movie the year you were born.
Working title: Group Hug
This epic on-screen team-up of several of Marvel’s biggest superheroes was a major enough film to require a totally unrelated working title during production. Writer-director Joss Whedon’s choice? Group Hug. Since the film takes several heroes, many of whom already had their own movies, and brings them together to save the world, this title seems appropriate. (Even though the heroes don’t get along too well until the third act of the film.)
And Group Hug isn’t the only fun working title in the Marvel Cinematic Universe. Captain America: The First Avenger worked under the title Frostbite, which seems apt considering that the titular hero ends up frozen in ice at the end of the movie. The sequel to The Avengers, Age of Ultron, had the working title After Party.
