Audio problem: During the song "Mark it Up", when Luigi stabs the Gen-tern, his lips briefly don't match the words he is singing.
Nathan Wallace: I'm the monster. I'm the villain. What perfection. What precision! Keen incisions, I deliver. Unscathed organs, I deliver. Repossession, I deliver. I'm the Repo! Legal assassin!
Trivia: Alexa Vega had gotten a tattoo of a cross on the bottom of her foot, and had to be careful during production to not let it be seen. She later stated it was a "stupid thing to do" in the DVD commentary. It is visible in a few brief instances, however, such as when she is on her bed, pretending to sing with Mag shortly before Rotti sends her the first message.
