The stunt coordinator on the film, Nils Allen Stewart (as Nils Stewart) is the father of lead actor Booboo Stewart, whose birth name is Nils Allen Stewart, Jr. One of the credited dancers is Fivel Stewart, the sister of the same lead actor. This film is literally a family affair.
At one point in the film, actor Tyler Posey mispronounces the name of Russian-American author Ayn Rand, in reference to her novel The Fountainhead. He pronounces her first name "AY-n," (as if to rhyme with "main," "bane," or "lane"), despite it's correct pronounciation being the exact same as the much more common English "Anne," (which rhymes with "man," "fan," and "can.") Whether or not this is a purposeful mistake is debatable, (as Posey's character claims not to've read Rand's novel), but seeing as his friend who has indeed read The Fountainhead fails to correct his pronounciation, it seems unlikely.
