Actors Charlie Sheen and Whoopi Goldberg are starring in a film about the September 11, 2001 attacks on the United States that began filming Monday.
The action-drama, titled simply "Nine Eleven," tells the story of five people trapped in one of the elevators of the World Trade Centre.
The WTC's Twin Towers collapsed after two planes crashed into them.
Shooting for the film, taking place in the southern California city of Long Beach, is due to last the entire month of March, in time for release later this year.
"It's a project eight years in the making. A miracle it's come together," Argentine director Martin Guigui, 50, told AFP.
The film is the first major project for "Two and a Half Men" star Sheen since he announced last year that he is HIV-positive.
The cast of "Nine Eleven" includes Puerto Rican actor Luis Guzman — known for his role in "Magnolia," "Traffic" and "Boogie Nights" — and Wood Harris, who played the role of drug baron Avon Barksdale in crime drama "The Wire."
