Schwartz video - Russ Meyer's Up (1976)

This kicks off with the murder of one Adolf Schwartz (who bears a striking resemblance to another famous Adolf) by placing a ravenous piranha fish in his bathtub. Who did it? No-one knows or cares, as they're too busy being distracted by busty Margo Winchester, who hitch-hikes into# town and gets involved with all the local men. It all ends with a series of complicated plot twists that reveal that just about everyone is really someone else. And if it gets too confusing, Russ Meyer helpfully arranges for a one- woman nude Greek chorus to pop up at intervals to explain what's going on.
