The Hollywood couple, who remain unmarried after nearly a decade together, will play husband and wife in a movie. Brad Pitt and Angelina Jolie, who remain unmarried in real life, will play husband and wife in a new film.Pitt, 50, is likely to receive a lesser fee than his wife who wrote the movie and will direct it, according to The Hollywood Reporter.The new film is By the Sea which has been described as an "intimate character driven drama" by Universal Pictures.Speaking to Extra TV earlier this year Jolie, 39, said: "It's not a big movie, not an action movie. It's the kind of movie we love but aren't often cast in. It's a very experimental, independent type film where we get to be actors together and be really raw, open, try things." It is the couple's first film together since Mr & Mrs Smith in 2005 which led to their off-screen romance. They now have six children together but have not married. Pitt has said they would not do so until same-sex marriage is legalised throughout the US and "everyone in this county had the right to get married." Jolie has said she intends to do less acting in future an focus on work behind the camera and her role with the United Nations.Donna Langley, co-chairman of Universal Pictures, said: "Angelina continues to showcase her extraordinary storytelling abilities in front of and behind the camera and we are thrilled to extend our relationship with her on By the Sea."Angelina and Brad represent two of Hollywood's brightest talents and we are excited to be a part of their collaboration on this powerful piece."
