Continuity mistake: At the end of the escape scene, Rita makes her way to the street by jumping down from one object to another. The last thing she lands on is a hammer handle sticking out of a filing cabinet. When Roddy attempts to follow her, he falls on the same objects that she jumped on to. The last thing he lands on, though is the head of the hammer that was absent from the handle when Rita jumped down.
Trivia: In the beginning when Roddy is waking up, a glass Alex the Lion (from "Madagascar") cookie jar is visible on the window sill. When Roddy is looking for something to wear, one of the outfits he holds up is Wallace's sweater vest from "Wallace and Gromit: Curse of the Were-Rabbit".
