A public feud has broken out between the Mexican movie making team of director Alejandro Gonzales Iñárritu and writer Guillermo Arriaga in the wake of the success of their latest film, Babel. As reported Tuesday by the Associated Press, Iñárritu, joined by actors Gael Garcia Bernal and Adriana Barraza and Oscar-winning composer Gustavo Santaolalla, said in a letter to Arriaga published in the Mexican magazine Chilanga, "It's a shame that in your unjustified obsession to claim sole responsibility for the film, you seem not to recognize that movies are an art of deep collaboration." Asked about the letter during a radio interview, Arriaga complained that Iñárritu was stealing credit for the movie by listing himself in the credits as the movie's creator.
