Paramount Pictures has been hit with a potentially headache-inducing lawsuit claiming that the studio had already lost its rights to Top Gun and that the latest sequel represents a copyright infringement. The suit, filed today in California federal court, comes from Shosh and Yuval Yonay, heirs of the writer Ehud Yonay, whose story in the April, 1983 issue of California magazine, entitled “Top Guns,” was source material for the original 1980s Tom Cruise classic. His story focused on pilots and their personal experiences, including a hotshot pilot “Yogi” and his radio intercept officer. According to the suit, Paramount licensed the magazine article within weeks of the story’s publication.
