Deliberate mistake: In countless shots showing Japanese, and some shots showing Americans, being shot, take notice of the ground that they stand on. Almost every time a bullet(s) will hit below them at their feet, yet they still fall dead. In some shots even, there is a continuous line of shots from a single shooter, hitting the ground, yet numerous Japanese soldiers fall dead.
Windtalkers (2002)
1 deliberate mistake - chronological order
Directed by: John Woo
Starring: Nicolas Cage, Christian Slater, Jason Isaacs, Peter Stormare, Adam Beach, Noah Emmerich
Factual error: The movie is set in 1944, when there were only 48 states, yet we see many American flags with 50 stars, then 48, then back to 50 throughout the film.
Joe Enders: Stay on my ass.
Question: Why do Nic Cage and Peter Stormare have metal chains for their dog tags while others all seem to be leather?
Answer: Marines (and other service members) wore their dog tags on the issued chains, or cords, string or other materials. This might have been for personal preference, available materials at issue, or replacement for breakages. So the costume designers probably copied this.
