Michael Moore’s Fahrenheit 9/11 made $23.9 million in its opening last weekend, making it the highest-grossing film of the weekend and the highest-grossing documentary ever (not including IMAX or concert films). Just like TV, reality is in.

“Documentary filmmakers have started to tell good stories, interesting stories, and have realized the word documentary should not be synonymous with castor oil,” Moore told AP in a piece about the rise of the documentary.

In addition to Moore’s election year success, he held the previous record for a documentary with Bowling for Columbine and had a rare hit with 1989’s Roger & Me. But Moore’s not the only one. This year’s Super Size Me, last year’s Spellbound, 2002’s skateboarding documentary Dogtown and Z-Boys, and 2001’s Winged Migration have all seen multi-million dollar success.
