From Cinematical (USA):
MPAA Censors Guantanamo Poster

Just a day after we reported on censorship in other parts of the world (assuming, perhaps, that films in the US escape such restrictions) comes the news that American authorities are getting into the act, as well. Fan-freaking-tastic.
According to press reports, the MPAA has objected to the poster that Roadside Attractions was planning to use to promote their American release of [movie] The Road to Guantanamo.
The original poster depicts a prisoner hanging from chained wrists, with a burlap bag over his head — nothing more, said Roadside president Howard Cohen, than a reflection of “what it is we are doing to people in Guantanamo.”
