Errors made by characters (possibly deliberate errors by the filmmakers): After the "Last Road to Hell" sequence, the female executive tells Professor Monroe that the footage was "all a put-on" and "there was no enemy army approaching," referring to the fact that the soldiers shown in the film were all acting. The Last Road to Hell sequence is made up completely of execution footage, with no soldiers acting or enemy army approaching at any time. This is because originally in the script, the sequence consisted of Vietnamese rebels firing at approaching troops, but execution footage from Nigeria was used instead.
