On Friday night, you get a character, a prop, a line of dialogue and a genre, all to include in your movie. 48 hours later, the movie must be complete. Then it will show at a local theater, usually in the next week. In 2010, nearly 40,000 filmmakers made 3,000 films in 80 cities on five continents. This year, we're even bigger, with filmmakers around the world taking the challenge to make a film in just 48 hours.
