Serial monogamist Leslie Mann has found herself yet another role to cement her legacy of being described as the wife in something. She's and Game of Thrones star Nikolaj Coster-Waldau are in talks to co-star in the Nick Cassavetes comedy The Other Woman. Cameron Diaz is already signed on to the film, playing oblivious girlfriend to the married Coster-Waldau. When she discovers that she is, in fact, The Other Woman, she teams up with Mann, who plays a character that may or may not have a name or distinct personality but THR helpfully paints as "the wife." Hopefully she will be pleasantly attractive and genial outside those times she becomes reasonably annoyed with her husband's childish behavior.
