"The Seventh Seal (Swedish: Det sjunde inseglet) is an existential 1957 Swedish film directed by Ingmar Bergman about the journey of a medieval knight (Max von Sydow) across a plague-ridden landscape. Its best-known scene features the knight playing chess with the personification of Death, his life resting on the outcome of the game."

I'm embedding it here, but it's best watched in "Double size" so that the picture can more easily be seen. If you want to watch it at 200% zoom, click on the Google Video menu (bottom right) to select "Go to Google Video." Once the page has loaded, open the menu on the bottom right of the player and select "Double Size."
The movie is 1h37m long and excellent. (It is #84 in IMDB's top 250 movies.)
Naturally, it's best to watch the movie from an actual DVD, but it certainly doesn't hurt to provide this movie for free here
