 The cast did many rehearsals, including on-location rehearsals, which Dennings described as "the most practical thing I've ever heard of".During the course of filming, the actors slept during the day, woke in the afternoon, had their make-up applied on set, and filmed from dusk until dawn.The cast and crew members would often sit inside The Jerk-Offs' van between takes to avoid the cold, and sometimes stayed inside, out of sight, while scenes were being filmed in the van.
