O.K there is a few a continuity's in this movie,although it didn't detract from me enjoying it any way heres a few..
1.n the scene where they are flying to Peru from US, they fly over a "map" of a Central America region and the country of Belize is shown. That country was the British Honduras until 1973. It was then renamed to Belize.
2.he movie supposedly is taking place in 1957, yet the motorcycle that Mutt rides is based on a 2000 or newer Harley Davidson softail, showing the modern day controls and Twin Cam motor.also the motorcycle has a front disc brake. You can see the master cylinder on the handlebars. Not available in 1957.
3. In the shot of the amazon jungle where they are driving with the enemies, at first they show a truck cutting the way through and forming what would be the road in a forest full of trees and woods. After the chopper truck is blown up, a road still exists, and there's even a double road when Shia and Cate Blanchett are fighting in between cars.
4. In the scene in the army warehouse where everything metal was being attracted to the magnetic crate, the Russians' guns should have been pulled away especially the ones that are slung across there backs, or at least toward the crate, as well.
5.He must be so proud of this movie.."Directed by Steven Spielberg" is shown twice in the opening credits.
6.Professor Ox is talking Mayan in the temple in Peru. In the Peruvian jungle, they speak Aymara. Mayan was spoken in Mexico, Guatemala and all Mayan countries. Also, the stone temple design shown in the Amazon was made by Mayans in such countries, not like the ones made by Incas in Peru.see images below...
