Slacker Uprising, which chronicles Moore's attempts to fire up the youth of America to vote during the 2004 election, will be available as a free download for three weeks from 23 September (08).
Moore says, "I thought it'd be a nice way to celebrate my 20th year of doing this, and also help get out the vote for November. I've been thinking about what I want to do to help with the election this year."
Moore's move marks the first time a major movie is released in such a way.
The director's last film, Sicko, was leaked online and downloaded illegally in large numbers.
