The monetary amount paid to the drivers is inconsistent throughout the film. The oil company first says they will pay "8,000 pesos to each driver". The driver's later demand double that amount (which would be 16,000 pesos). Later when Scanlon crosses the rope bridge he boasts that the two of them will get "double shares of 20,000 apiece" (double shares would actually be 32,000 apiece). At the end, Scanlon is given a check for 40,000 Dollars.

During the tree sequence, after the dynamite is lifted out of the wooden crate, it is kicked to the side and (apparently) falls off the tree.

Weeping dynamite is leaking out the nitroglycerin as a liquid which will readily soak through untreated materials such as the wooden case, shelves upon which they sit and so on. Old stocks of dynamite usually require destroying the entire building in which they are found for safety.

When kicked, or when it fell to the ground, the wooden crate would have exploded with significant force. The drivers would have been briefed on this to not make any mistakes while moving the crates.

It would be futile to mount a suppressor on the revolvers used in this film, and almost every other one, because the sound still escapes through the gaps between the cylinder and frame/barrel.

It is not possible to adjust or even measure valve play while an engine is running.

One of the soldiers killed by Nilo is seen breathing and moving after dead.

When Sorcerer is attempting to cross the dilapidated wooden bridge, a shot of the outermost log falling away is used twice.

In the wide shots of the trucks crossing the bridge, the tow cables/anchor lines to the bridge can be seen going in and out of the water as the bridge rocks back and forth.

In Scanlon's first scene outside church wedding, he already has a very visible bruise on right jaw. It makes one question how he got it. It becomes apparent in the next scene that they must have filmed out of sequence. Also, his nose is obviously made up without a bridge bump, until later it's as if his natural nose is a result of the prior accident.

When the DC-3 plane lands on the dirt runway, a sound effect of squealing tires is used. Tires cannot squeal on dirt.

By the late 1970s, helicopters were routinely used to transport high explosives, even in Third World countries. Therefore, there was no need to use a truck convoy, as in The Wages of Fear (1953).
