If you buy the extended DVD of 'The Great Escape', as one of the special features, you get the option of watching it with 'trivia' appearing on the screen. It gives little potted biogs of the actors and the people (or amalgum of people) they were portraying, historical facts about the situations, snippets of info about the making of the film and some wonderful insights into the real story.

It's well worth the money and makes a whole lot more sense of some situations.
