The Hollywood Reporter reports that Hilary Duff will join the comedy "Stay Cool," which will also co-star Winona Ryder, Mark Polish, Sean Astin, Chevy Chase and Jon Cryer. The film is being written by Mark and Michael Polish. Michael Polish will direct the movie.

The trade describes the project as a "knowing-your-age comedy," centering on a successful author (Polish) who is forced to confront an unrequited high school crush (Ryder) when he returns home to deliver a commencement address to graduating seniors. Duff will portray Shasta O'Neil, a sexy high school senior who flirts with the visiting author and invites him to the prom.
