As pleasantly surprised as I was by last summer's musical remake of Hairspray, I can't say that the prospect of sequel potential ever once came to mind. Thankfully, that's why we have Hollywood bean counters and the like, who see the success of that film, Mamma Mia! and High School Musical (including a fair amount of CD and DVD sales for each) as reason enough to have John Waters -- who wrote the 1988 original -- whip up a treatment for a Hairspray sequel.
According to Variety, returning for the project is director Adam Shankman and ... um, no one else at the moment. There isn't a writer attached, nor are any of the original stars lined up to return, although I have little reason to think that most of the young cast wouldn't be down for another one (just what is Nikki Blonsky up to now, anyway?).
Warner Bros. hopes to have Hairspray 2 (Hairspray-ier?) in theaters by July of 2010.
