According to Variety, New Line Cinema has asked for a sequel to "Hairspray."
John Waters has been contracted to write a treatment, Marc Shaiman and Scott Wittman have agreed to do the songs, and Adam Shankman has agreed to direct and choreograph.
They plan to open the movie in July 2010 (The Year We Make Contact).
None of the actors have signed yet, but they hope to reassemble most (if not all) of the original movie cast.
So if you thought the "movie of the stage musical based on the movie" was odd enough, we'll have the "SEQUEL to the movie of the stage musical based on the movie."
The biggest strength I see here is that John Waters is responsible for writing the story.
Wouldn't it be great if Tracy grows up to be Divine (which would make Edna turn into Edie the Egg Lady).
