Alejandro González Iñárritu has found the foil for his first comedy film…

The 49-year-old Mexican filmmaker, known for dramatic films like 21 Grams, Babel and Amores perros, has cast Edward Norton in his dark comedy Birdman.

From Fox Searchlight and New Regency, the film will center on a former actor ( played by Michael Keaton) who once played a superhero who puts together a play on Broadway based on a short story by Raymond Carver. Unfortunately, the ex-superhero’s plans to soar again are threatened by his egotistical lead stage actor portrayed by Norton.

Along with Norton and Keaton, the cast includes Emma Stone, Naomi Watts and Zach Galifianakis.

The film will be shot in a Broadway theater in New York beginning mid-April.
