According to Deadline, Sean Penn is considering The Last Photograph, along with Christian Bale. Bale is apparently playing a war correspondent who witnesses an attack on a group of Americans and is the only survivor.
Meanwhile, Penn is circling the role of a retired special operations soldier who comes to the scene hoping to free a family member who's been kidnapped. The correspondent offers to help identify the kidnappers and help find them in exchange for being able to write an article about the entire thing.
The film came about after an idea from director/producer Zack Snyder. The film will be directed by Niels Arden Oplev, who directed the Swedish version of Girl With The Dragon Tattoo.
Dark Castle is in negotiations to finance and produce the film, although it was originally hatched at Warner Bros.
