The Boat That Rocked

The official synopsis of The Boat That Rocked before release stated that it tells the fictional story about a group of DJs in 1966 who are at odds with a traditionalist British government that prefers to broadcast jazz. According to director Richard Curtis, the film, though inspired by real British pirate radio of the 1960s, is a work of historical fiction and does not depict a specific radio station of the period.
