The thumb that is shown when Jessica the R.A. hands Vincent and Nick their roommate contract actually belongs to the casting director, Amanda Araque.
Ernesto Rojas, the voice of Alec, originally appeared in multiple scenes with Nick, playing a friend that Nick met at freshman orientation. However, due to time restrictions, director Bryan Firks decided to leave Alec's scenes out of the final cut and only introduce the character via a phone call.
