Duck, You Sucker!
The reasons for this are varied, but usually point towards marketable, linguistic or cultural differences. Some titles may not be easily understood in other parts of the world, and may even be considered offensive. Most title changes are commercial. An example is Italian director's Sergio Leone's 1971 film "Duck, You Sucker!", initially released with this title as he was convinced it was a well-known English saying. When the film performed poorly, it was subsequently rebranded as "A Fistful of Dynamite", similar in name to his 1964 film "A Fistful of Dollars", part of the successful Dollars Trilogy.
