While we try not to discourage deeply personal art, the audience will likely see right through the scene in which the protaganist is captured by enemy soldiers and drunkenly asks if they are Jews. Mayans had no knowledge of the existence of the Jewish people! Also a little too transparent is the part where the enemy soldiers remark that these “must be the drunken ravings of a mad man” and that they should “do what any civilized society would do and not blow this out of proportion.” The scene then ends with them noting that they should “make sure they continue to see this guy’s movies.”
While it is true that Mayans offered human sacrifices as gifts to their gods, no one would have been concerned about “scratching the price tag” off of the sacrificial gift. You should also get rid of the scene where the two warriors show up with identical twins and worry that they “both got the sun gods the same thing.”
You are correct that the Mayans would sometimes launch bees’ nests and poisonous frogs upon their enemies, however, these creatures did not explode into flames on impact, as you suggest here.
While the Mayans were known to have tattoos, the words “Tru Playa 4 Real” meant nothing to the people of that time period, especially in English.
