Continuity mistake: The number and location of the blue gas containers that fell out of the rear of the station wagon change. Initially, three containers fell out. Only one was visible on the road and it was to the side of the rear bumper, not on the road where it fell/ landed. Next, no blue containers are visible on the road, followed by one container being behind the passenger side rear tire. No blue containers are on the road when the goat comes out.

Revealing mistake: The backgrounds during the pawn shop scenes often change, suggesting the use of a "green screen." For example, the grandfather clock was behind the clerk to his left, then not there, but back again. Sometimes shirts are hanging in the front windows but other times there are other items there.

Continuity mistake: When the goat is in the back seat, its position changes with camera views a few times. For example, it was facing towards the passenger side, then its head was between the front seats. Also, it looks more like a mechanical goat more often than not. (00:55:57 - 00:56:26)
Continuity mistake: The belongings that the half-brothers packed into the cargo area of the vehicle are inconsistent many times during their trip. Sometimes, none of the belongings can be seen through the windows. (00:28:09 - 00:57:45)
Factual error: Renato and Asher could not just fly from the USA to Mexico; they'd need permission to fly and crossed a border without a passport.
