New Line Cinema announced plans today to make another Hairspray movie after making a deal with John Waters.

Waters was the writer and director of the original 1988 version, which was then adapted for Broadway in 2002. He produced the successful 2007 musical and will write the treatment for another story. Adam Shankman will return to duties as director and choreographer.

After the massive opening for Mamma Mia! here and overseas, Warner Bros (owner of New Line) sees more potential in the musical business. Plus High School Musical gave them the bright idea that musicals could be a franchise. Hairspray set the record for biggest opening for a musical. Then Mamma Mia! (at Universal) broke it. I guess WB wants to reclaim the title.

Both were released in mid-July, so New Line is targeting a mid-July 2010 opening for Hairspray 2.

No cast has been officially attached to return. Nikki Blonsky’s first movie was Hairspray, so she’ll likely be back as the star of the second film. Other cast members to hire back are Christopher Walken (the legend), John Travolta (in drag again), and Amanda Bynes (ultra cute). They could probably do without some of the supporting cast like Zac Efron, James Marsden, Queen Latifah, and Michelle Pfeiffer.

I’ll admit I liked the movie. With all heterosexual expectations against it, I ended up enjoying it. Having said that, I don’t want to see a sequel. But I wouldn’t mind seeing more of Amanda Bynes.
