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.
Not about an iguana nor taking place at night, this adaptation of the Tennessee Williams play is heavy on melodrama and earnest performances, but weak on dialogue and lasting meaning. Richard Burton is justly celebrated for his role as a defrocked priest (from, ahem, "St. Jame's Church") now making a living as a Mexican tour guide, but the three banshees he has to deal with (and which form the basis of the rudimentary plot) are nothing you might consider message-bearing. In fact, if the good priest had simply run the other way instead of meddling with any of these three ladies, he'd have been better off. And the movie would have been a heck of a lot shorter.
