Eric Christian Olsen was repeatedly denied the role of Lloyd because the producers thought he was "too good-looking". It was only after seeing some home-video footage of Eric in full make-up improvising a scene with already-cast Derek Richardson that they gave him the role.
In one scene, Lloyd is looking at a pottery magazine, sees a large jug, and says to Harry, "Your mom has jugs like these!" to which Harry replies, "Yeah, but hers were never in a magazine." In fact Mimi Rogers, who plays Harry's mother, posed for Playboy in 1993.
Rick Hoffman later appeared with both Eric Christian Olsen and Derek Richardson in different films: Olsen in Cellular (2004) and Richardson in Hostel (2005).
