Two movies come to mind.
"Clash of the Titans". Total bastardization of Greek myth. Harry Hamlin talking to a metal owl. Burgess Merideth looking all kinds of sincere. And totally groovy special effects.
"Straight to Hell". Looks like the director who made "Sid and Nancy" and "Repo Man" had some spare cash and leftover film to kill, so he invited a bunch of friends out to the desert to make a Gad-awful western. Every line is ad-libbed. Every scene is arbitrary. But check out the stars: The Pogues (as Mexican bandits), Elvis Costello as a waiter, Joe Strummer as a bank robber, Courtney Love as a gangster's moll. Grace Slick and Dennis Hopper have cameos. The scene where the cast tries to conduct a funeral without killing anyone is a riot.
