Factual error: An An-12, the aircraft the main character uses to fly all over the world, has a maximum range of about 3,500 miles. Hardly enough to fly from the US to South Korea or from South Korea to Israel. The An-12 also miraculously transforms into a C-130 in a couple of filler scenes. And why is this ex-Soviet aircraft marked in USAF markings, assigned to McGuire AFB?
Factual error: When we are at the Welsh WHO facility we get an exterior shot during the night where we hear crickets chirping. This is a classic US film-making error. There are no crickets in Wales or any part of the UK. What you would hear at night is silence. Maybe owls.
