It seems like it has been an eternity since Cate Blanchett signed on for the lead role in the movie adaptation of Where'd You Go, Bernadette. (OK, it has been since November 2015.) Now, the rest of the characters are being cast, slowly but surely. Richard Linklater is directing the film, based on Maria Semple's 2012 bestseller, and we couldn't be happier about the choices so far. Now that it has gotten a Mother's Day 2018 release date, check out everyone who has been cast so far.
