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)
Suggested correction: "Juanillo" is another, though less common, diminutive of Juan.
I can appreciate you doing a google search but you would have noticed in your google search that the Juanillo you speak or is predominantly an Asian name and is not a translation of Johnny in Spanish. I am Spanish and can assure you that it was a mistake as Juanito is the correct pronunciation. Thank you for doing your due diligence however he was not playing the role if an Asian.
It should be pointed out that there's a town in Mexico called Juanillo and Juanillo Beach is in the Dominican Republic. So it is a word Hispanic and Latinos might be aware of.
Don't know why the previous guy said that Juanillo is not a common name in Spain... I am Spanish and know 2 guys that go by the name Juanillo. I would say that not only Juanillo and Juanito, but also Juanele are commonly used in Spain and probably Latin America as well.
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.
