Helmer Todd Graff is in negotiations to direct the Sarah Jessica Parker starrer "Slammer" for Revolution Studios reports Reuters.

Described as in the vein of "Private Benjamin," the story centers on publicist Maggie Ray (Parker), who is framed for theft and shipped to Sing Sing Prison in New York. In an attempt to polish the prison's image, she produces an inmate-led musical that could save her career.

"Hairspray's" Marc Shaiman and Scott Wittman will compose the songs and score for the musical-comedy. Sara Goodman penned the script, based on a story by Tim Metcalfe and John Slotnick.
