Who's Afraid of Virginia Woofe? Best performance ever by a female actress. Elizabeth Taylor is just incredible in this movie. It's a movie that's hard to watch if you haven't seen it, but it's great to see Taylor and Richard Burton (her real-life husband at the time) just verbally rip each other apart. Hard to tell if they're acting. :)
Who's Afraid of Virginia Woolf? (1966)
Like Water for Chocolate, one of those that you think about often even years later.
