The Girl on a Motorcycle (French: La motocyclette) is a 1968 British-French erotic romantic drama film directed by Jack Cardiff, starring Alain Delon and Marianne Faithfull and featuring Roger Mutton, Marius Goring and Catherine Jourdan. It was listed to compete at the 1968 Cannes Film Festival but the festival was cancelled due to the May 1968 events in France. The Girl on a Motorcycle redefined the leather jacket for motorcyclists into a catsuit that Faithfull wore in the film. It was the first film to receive an X rating in the United States. Edited by Warner Brothers to get an "R" rating, the film was released as Naked Under Leather in the United States.
