Jennifer Aniston joins a fairly impressive cast for this one, including Julia Roberts, Timothy Olyphant, and, erm, Jack Whitehall. From director Garry Marshall, whose credits include Pretty Woman and creating Happy Days, this will be a comedy featuring intersecting stories of different mothers on, well, Mother's Day. So basically a bit like that day's equivalent of Valentine's Day or New Year's Eve, both of which Marshall also directed. Release Date: April 29
