Once Upon a Time in Mexico

Factual error: When Antonio Banderas gets shot with the dart in the forehead there are two reasons why that wouldn't work - 1) There isn't any muscle tissue and the skin is too thin for the dart to stick most likely. 2) The tranquilizer would never take effect that quick unless it was injected into a muscle where the blood supply is greater.

Factual error: In the flashback scene when El Mariachi and Carolina are getting married, the chain is cut with a process called MIG (Metal Inert Gas) welding. This is a welding, NOT, a cutting process. While it can be done, the heat generated would have burned both wrists. (00:34:50)


Factual error: When Sands throws Bellini's body into the water it floats like on the Dead Sea, as if it's made out of cardboard - barely submerged at all. (00:38:30)


Revealing mistake: Near the end of the movie, when Johnny Depp's eyes are removed, he talks with the boy when he's against the wall. In several shots you can see Johnny Depp's eyes through the sunglasses (01:33:55)
