What Is The One Movie Everyone Must See (At Least Once)

My coworkers and friends are shocked and awed that I have not seen the movie Top Gun!

It's not that I haven't tried, it's just that airplane movies don't really appeal to me except for the movie, Red Tails.

Name a movie that you think everyone must see at least once.

Here is my top three:

Gangs Of New York

Selena

Harlem Nights

Anchorman: The Legend Of Ron Burgundy

The Pianist
