Another cinematic power-duo has hit the dust. In the 90's, it was Quentin Tarantino and Roger Avary. While the details have remained fairly tight-lipped, the duo, who had originally met at a video store in the 80s, went their separate ways after the release of their mega-hit, Academy screenplay winner, Pulp Fiction. Rumor has it that Avary felt that he wasn't given proper credit for his work on the film. Now, over a decade later, Guillermo Arriaga is spouting similar claims following the split between himself and film parter Alejandro González Inárritu.

The pair were largely responsible for the rise of contemporary Mexican cinema. Together, they brought us three high-impact dramas -- Amores Perros, 21 Grams and Oscar nominee, Babel. Now, they don't speak to each other, which could make things very interesting come Oscar night -- they've got a whole slew of nominations, so chances are the film will win something. While Inárritu doesn't seem to be saying much about the split, Arriaga is making up for it. He is not happy with those who consider the three films González Inárritu's trilogy, and he swears that the ideas pre-dated their collaboration. His ex-partner, on the other hand, says that Babel was his idea, that Arriaga wasn't his first choice and that the writer's words were overhauled.

The partnership was far from smooth, and perhaps their antagonism is what made their collaborative efforts so successful. Their solo work has not equaled the success of their joined work, although Arriaga's The Three Burials of Melquiades Estrada came close when it scored a best screenplay award at Cannes. Perhaps he is right, and audiences should pay more attention to the writing credit, and the director.
