40. 'Endless Love' (1981)
This notorious melodrama starring Brooke Shields and where-is-he-now? casualty Martin Hewitt as star-crossed teenaged lovers torn from each other by a series of hilariously unlikely events is one of the seminal bombs of the 1980s. Tom Cruise has a teeny-tiny part in it, but he compounds the awfulness thanks to the fact that he gives Hewitt's romantic hero the ludicrous idea of setting his girlfriend's house on fire in an attempt to get back in her family's good graces. On the plus side, he is shirtless.
