When a character's name enters the language as a general descriptor of a similar person, you know you're dealing with a classic. Lolita is exactly that film -- and the story of one man's obsession with his stepdaughter is so well-known it scarcely requires explanation. If you've never seen the original, you need to, and soon. While it's far too long at over 2 1/2 hours, these characters are so juicy and delicately balanced (this was 1962 and pedophilia was hardly accepted on film) they're a true must-see. Remade in 1997.
