Christopher Walken is in talks to star in 'Wild Oats'.
The action comedy tells the tale of a grandmother (MacLaine) who runs away to Las Vegas with her granddaughter (Ricci) when she is suddenly given a cash windfall, according to The Hollywood Reporter.
Agathe David-Weill and Blythe Frank are directing the project - although Walken's possible role in the movie is not yet know.
Filming on 'Wild Oats' is due to begin in August.
Walken has worked on a number of well received films in the last decade, including 'Sleepy Hollow', 'Catch Me If You Can' and 'Hairspray'.
