Emma Watson has reportedly signed up to star in a new film by Perks of Being a Wallflower director Stephen Chbosky.

The actress is teaming up with the director on a new film based on the concept of body swapping, according to Deadline Hollywood.

The film, While We’re Young, is based on Adena Halpern’s novel 29, about a young at heart 75-year-old grandmother who would rather spend time with her 29-year-old granddaughter than her 55-year-old daughter.

On her birthday she is granted a wish and becomes 29 again, spending her time having fun with her granddaughter.

Michael H. Weber and Scott Neustadter, who penned indie rom-com (500) Days of Summer, will write the script.

Watson won a People’s Choice Award earlier this year for her role in teen drama Perks of Being a Wallflower, which Chobsyk adapted from his own bestselling novel.

The actress, who recently appeared in Sofia Coppola’s The Bling Ring, is due to star in Darren Aronofsky’s Noah next year.
