Based on the short, titled "Slumber Party Alien Abduction" from found footage horror anthology sequel V/H/S/2.
Filmed in the house owned by director Jason Eisener's parents. The same house was used for Eisner's V/H/S/2 segment "Slumber Party Alien Abduction".
The extras for the Halloween party were students from a theater school.
The scenes in the alien slime chamber were done in two days.
