A lot of people thought “The Hurt Locker” was a documentary because it was shot on videotape, but there was a blooper that made that impossible. Early in the movie, a soldier is defusing an IED, and “There’s an Iraqi with a video camera; he’s probably going to put this on You Tube.” The movie is set in the fall of 2004, and You Tube didn’t debut until early 2005.
