Beyond the Doors (1989)

Synopsis
According to this film by no-budget auteur (and conspiracy buff) Larry Buchanan, singers Janis Joplin, Jimi Hendrix and the Doors' Jim Morrison didn't die of drug overdoses; in fact, Morrison didn't die at all! The government sent an assassin (who got the job because he didn't like his son listening to rock 'n' roll records) to kill them because they were trying to influence young people to protest against the Vietnam war. Hendrix and Joplin were killed by the assassin, but Morrison faked his death and hid out in a monastery in Spain. Oh well, stranger things have happened . . . ~ Brian Gusse, All Movie Guide
