Hollywood movies are remade for distribution in nations around the world, which requires subtitles or dubbing the dialogue for non-English countries. But often there are other changes, too, like the title. American movie titles are often shortcuts that are well understood here, but may not have any meaning somewhere else. What the movies you know and love end up being called elsewhere can surprise you. It's not only slang terms or politics at work. Some titles are made more descriptive to draw an audience in, although this one may have given too much away.
One movie title was changed to distance itself from a porn star of the same name. How does a porn star become so famous that people might mistake an animated Disney film for one of hers? See 19 of these changed titles at Cracked.
