Revealing mistake: When John and Lacey brand a calf it doesn't even wince when the iron hits the skin. It looks as if in Mexico they do branding under anaesthetic. (00:30:55)

Revealing mistake: When Alejandra comes to John's room the first time you see distinct t-shirt marks on John's upper body, his arms as tanned as his neck and face. This in spite of the fact that he wears long-sleeved shirts throughout the movie (except, of course, during his nightly encounters with Alejandra). (00:49:30)

Revealing mistake: When they break in the mustangs you see in at least one shot that stuntmen do the rodeo riding. Matt Damon's is wearing different shoes. (00:34:50)
