"The Island" is a copy? The answer is "yes" according to Myrl A. Schreibman and Robert S. Fiveson. These producers of a 1979 film entitled "Parts: The Clonus Horror" claimed they have found a number of similarities between the two films and therefore placed a lawsuit against DreamWorks and Warner Bros as the distributors of "The Island."
Moreover, they also pleaded the court to order the studio to withdraw the film and block further release. Meanwhile, DreamWorks responded by denying the accusation, saying: "'The Island' was independently created and does not infringe anyone's copyright."
