Emma Watson is set to reunite with Perks of Being a Wallflower director Stephen Chbosky in his next film.

While We’re Young is a story about a 75-year-old woman who feels she has more in common with her 29-year-old granddaughter than people her own age. The story sees the woman make a birthday wish to be young again and it comes true.

The screenplay is an adaptation of 29 by Adena Halpern and has been adapted by Michael H Weber and Scott Neustadter, the pair who penned (500) Days of Summer.
