Emma Watson is teaming up again with director Stephen Chbosky (Perks of Being a Wallflower) to star in While We’re Young. The film is an adaptation of Adena Halpern’s novel 29 which tells the story of a 75 year old grandmother who gets her birthday wish to be 29 again for a day and has an adventure with her granddaughter. No other cast members or a date for filming have been announced. (This is not the Noah Baumbach movie of the same name which is currently filming.)

In the novel, Ellie Jerome is a young-at-heart seventy-five-year-old who feels she has more in common with her twenty-nine-year-old granddaughter, Lucy, than her fifty-five-year-old daughter, Barbara. Ellie’s done everything she can to stay young, and the last thing she wants is to celebrate another birthday. So when she finds herself confronted with a cake full of candles, Ellie wishes more than anything that she could be twenty-nine again, just for one day. But who expects a wish like that to come true?

29 is the story of three generations of women and how one magical day shakes up everything they know about each other. While Ellie finds that the life of a twenty-something is not as carefree as she expected, the sheer joy of being young again prompts her to consider living her life all over. Does she dare stay young for more than this day, even if it means leaving everyone she loves behind?

Fresh, funny, and delightful, 29 is an enchanting adventure about families, love, and the real lessons of youth. – Amazon.com
