7. 'I Love You to Death'

Harlan, Marlin and Deco (William Hurt, Keanu Reeves and River Phoenix) in 'I Love You to Death' (1990)

When pizzeria owner Rosalie (Tracey Ullman) decides to knock off her cheating husband (Kevin Kline), lovesick employee Deco is only too happy to take the contract, but after various tactics (including poisoned pasta) fail to do the trick, he subcontracts out to a couple of stoners, Harlan and Marlin, who fare no better. It's no stretch to see Phoenix and Reeves as slack-jawed slackers, but Hurt (who usually plays tweedy academics and intellectuals) brings unexpected depth -- er, shallowness -- to his role.
