The new comedy The Sisters Grimm, which offers a playful twist on the Cinderella story, will bow Off-Broadway in October, confirmed co author Madison Tyler, who penned the Florida hit with James Doyle. Theatre, dates and the exact producing team are yet to be determined.

As Playbill On-Line reported last July, interest in the show snowballed after a Miami Beach workshop during the 1999-2000 season. The production was greeted warmly by local critics and the six-week run quickly sold out.

The tuner tells the Cinderella story from the point of view of her wicked stepsisters. Evil siblings Licinda and Fabella Grimm are now 110 and 108, respectively, and the glass-slippered girl has gone on to meet her maker. With Cinderella out the way, the sisters want to set the record straight.

As ever, the two are capable of anything. They smoke, drink and wrap their hair while they unfold the story, which involves sex, murder, drugs and other family secrets. Meanwhile, they angle to cash in on their famous stepsister's celebrity, fishing for corporate sponsorship and a sale of the movie rights.

Cinderella and her stepsisters are also characters in the current Broadway revival of Stephen Sondheim's Into the Woods, now in previews at the Broadhurst. —By Robert Simonson
