Before there was "Mean Girls," there was "Heathers." Now that dark comedy is ready to bully its way into New York as a musical.

The 1988 film starring Winona Ryder, Shannen Doherty and Christian Slater has been turned into a show by Tony Award nominee Laurence O'Keefe and Emmy Award winner Kevin Murphy.

It starts performances off-Broadway in March at New World Stages after a stint in Los Angeles this year. Andy Fickman directs.

It tells the story of a high school misfit in Ohio who teams up with her boyfriend to kill her mean but popular classmates _ most called Heather _ and make it look like suicide.

O'Keefe wrote the music and lyrics to the Broadway show "Legally Blonde" and Kevin Murphy penned the lyrics to "Reefer Madness."
