The voiceover line "Your entrails are your extrails" is almost identical to a line spoken by Alan Tudyk's character 'Wat' from A Knight's Tale (2001). Wat threatens Geoffrey Chaucer with "Your entrails will become your extrails."
Grace, the voice over director, is played but Gina Torres. Gina also played Alan's wife, Zoe, on Firefly (2002) and Serenity (2005).
