The Foley artist chose the wrong sound effect for the camera used by the recon team in Somalia. The camera used is a Canon 20D digital SLR, while the sound produced when the operator releases the shutter is that of a 35mm film SLR with a motorized film drive. Since digital SLRs use an imaging sensor instead of film, they do not need a film advance drive and would not make that sound. Instead, you would hear the click of the shutter followed by a much more rapid whir of the shutter curtains being reset. See more

Alternate Versions

The patriotic tone of the film has been toned down for the international version. For example, in the original US version the letter says "Before my father died, he said the worst thing about growing old was that other men stopped seeing you as dangerous." In the international version it reads "Just before my father died, he said the worst thing about growing old was that it gets harder to protect the things that matter." Another example is the text at the ending. The US version shows the line "This film is dedicated to the following warriors of Naval Special Warfare who have made the ultimate sacrifice since 9/11." while the international version reads "This film is dedicated to all of the men and women who have sacrificed for their countries as guardians of freedom against forces of terror and tyranny."
