Hairspray, a remake of John Water's 1988 cult classic of the same name, has finally hit the $100 million mark. According to Variety, it is only the third recent musical to make that much at the box office. Chicago and Dreamgirls have also hit that financial landmark.

The film, directed by Adam Shankman, is the 10th musical in film history to reach this touchstone. The list of financially capable movies includes The Sound of Music and Grease, as well as such animated musicals as The Lion King and Aladdin.

Analysts suspect that tween girls are the reason the film is so popular. But the film also appealed to a much wider demographic than most of the recent musicals that have come our way. New Line president of distribution David Tuckerman stated, "We knew from before the picture was even released how much fun it was. But we also knew the challenge was to get males to come too, which they did. The movie just delivered."

New Line is hosting musical sing-alongs in 100 theaters across the country. At least $2 million has been made from this single venture alone.
