Writer-director Noah Baumbach is readying his next project, While We're Young, and has attached Ben Stiller and James Franco to star, reports Vulture.

Greta Gerwig and Cate Blanchett have been offered roles, but nothing is confirmed.

The script is being kept under wraps, but the story centers on a free-spirited Brooklynite twenty-something couple (James Franco and Greta Gerwig) who inspires an uptight documentarian (Ben Stiller) and his wife (Cate Blanchett) to loosen up - with comedic consequences.

No production date has been set.
