Continuity mistake: Hydell (the crazy brother) locks The Warden in the airlock. He begins to write "BI BI" in the condensation on the glass. The positioning of the letter 'I' in the first "BI" changes as the camera switches inside the airlock. It is now touching the first letter 'B'. Also the second letter 'B' is now much neater.
