Trivia: Some of the crew members and background extras were also a part of the film "Repo: The Genetic Opera", which has a similar premise. Story goes that Universal wanted to make "Repo", but backed out after the producers refused to meet their demands.

After leaving the project, Universal then announced this film (then titled "Repossession Mambo") and reportedly approached cast and crew members from "Repo" to come over and work on this film. The creators of "Repo" have made it clear that they feel Universal was merely trying to spite their production by poaching cast and crew members who were unaware of the falling-out between "Repo" and Universal execs.
