AceShowbiz - Maggie Gyllenhaal is preparing to set Hollywood buzzing with a racy new role - she's signed on to star in a film about the invention of the vibrator. The "Secretary" actress will play the daughter of a doctor in Victorian England, who created the sex toy to treat hysteria, which will be the title of the risque movie.

"Hysteria" will also feature "Evita" star Jonathan Pryce and Hugh Dancy, who will play the inventors of the new electrical device, while Rupert Everett will also star. Gyllenhaal says, "I play a firecracker whose father is a doctor who is in the business of curing hysterical women."

"He cures them basically by getting them off and that actually happened. I end up having a sort of unexpected love affair with this guy who works for him, and who by mistake invents the vibrator." The film is slated for a 2011 release.
