It was all filmed at Daniel Mart house. Because of this, at one point during the scene in which Erick and Daniel were trying to leave the room they were trapped in (which happened to be Daniel's bedroom), Daniel's younger sister thought that they had actually gotten trapped in the bedroom and thus opened the door hence ruining that take of the scene. Everything was then explained to her and she left afterwards calling them both stupid for doing this to begin with.
In real life Erick Carcamo favorite pizza topping is cheese and Daniel Mart favorite pizza topping is pepperoni.
The scream that Erick Carcamo does at the very end was meant to be longer but it was shortened as he was annoyed by his own scream. Daniel Mart wishes he would have kept the whole scream in there.
