Character mistake: When Cyrus and Johnny-23 are talking they both pronounce the Spanish version of Johnny-23's name as Juaniyo. That is not how Johnny is pronounced in Spanish. It is pronounced Juanito with a T. Normally I would have chalked it up as a language barrier but Danny Trejo is of Spanish ancestry. He should have known better. (00:20:41)
Character mistake: When they decide to crash land the plane and touch down on the road the pilot either doesn't cut power to the engines or doesn't shut them off. Towards the end, it looks like the engine is still at full power.
