She might be headed back to high school, but Hilary Duff is certainly not headed back to high school men. The Hollywood Reporter posts that the actress has joined the ranks of Stay Cool -- one of those Polish brothers projects that Eugene discussed back in May.

By signing on to the feature, she's joining the strange yet irresistible cast which already includes Winona Ryder, Mark Polish, Sean Astin, Chevy Chase, and Jon Cryer. It's an '80s explosion across the board! I'm sold just on the combination of Ryder, Astin, Chase, and Cryer.

Anyhow, the film is being described as a "knowing-your-age comedy," which focuses on a successful author played by Polish. He returns home to give a commencement speech at his old high school, and has to confront his unrequited high school crush (Ryder). But while he's remembering past lust, he becomes the object of Duff's affections. She will play "Shasta O'Neil, a sexy high school senior who flirts with the visiting author and invites him to the prom."

The film will shoot in Santa Clarita, California next month.
