Adam Green and Corri English choreographed the first half of their big dance number mere moments before shooting it and surprised the cast and crew with the routine on the first take. Only the second half of the dance number had been performed at rehearsals and was expected. The take was unusable due to the cameras shaking from each operator's laughter and the background actors breaking out laughing, but eventually the crew was able to hold it together to shoot the scene.
Actors Nick Ballard and Natalie Fabry (who play "Kevin" and "Carrie Ann") got engaged in real life mere weeks before portraying a married couple together on Holliston.
Oderus' Spooky Dan Bear is a nod to Spooky Dan, a prominent personality and activist within the horror culture and a close personal friend of Adam Green and Joe Lynch's.
Director Sean Becker plays the "Supreme Being" face inside Joe's bedroom. The gag is homage to TIME BANDITS, one of Green's favorite movies as a child.
