Girl On a Motorcycle (1968)

The cinematic equivalent of artificial fruit, this is one of a few thoroughly oddball projects directed by master cinematographer Jack Cardiff, and disconcerting proof that anything will seem stylish if it thinks it is and you leave it long enough.
In a role originally intended for Susan Denberg, Marianne Faithfull is in and out of a zip-up leather catsuit, while Alain Delon plays a master seducer in bobble hat and sandals. Some ludicrous soliloquies, dopey back projection, and a tragic ending that will keep you laughing for hours.
