Dermot Mulroney just finished tweaking his cast for Love, Wedding, Marriage, a romantic dramedy set to start filming on April 19th. Mulroney has cast Mandy Moore (License to Wed) in the lead as a newlywed marriage counselor looking to save her own parents from an impending divorce. Along with Moore, Kellan Lutz (of Twilight-series) will play her husband, while James Brolin and Jane Seymour will play the splitting parents. The cast and financing have been in a constant state of flux since the movie’s inception, and while the former is still getting ironed out, the latter is set to go. Mulroney has a plethora of acting credits, but has never stepped behind the camera before.
