The camera pulls back, zeros in on the base of a huge chimney and pans upward to the very top - where two men in black and white checkerboard jackets are working.
Revealing mistake: At the end of the movie, where Sgt. Eversman talks to the dead Corporal Jamie Smith about Blackburn, he says he's gonna talk to Smith's parents when he gets home. When Eversman places his hand on the chest of Smith, you can see his eyelids move. (02:14:08)
