Continuity: When the hotel worker is speaking to Aldous about his demo CD, Aldous sits with his whole body facing forward. After the hotel worker does his English accent, Aldous says, "That stupid English voice, was that me?" and he sits with his whole body facing the hotel worker. The hotel worker then says, "You're really going to like it," and Aldous sits facing away, before finally Aldous says, "I'll listen to it" with his feet on the ground, facing forward, before it immediately cuts to him saying, "When you've gone". He now sits facing the hotel inspector with his feet on the seat.

Revealing: When they meet up for dinner (Aldous, Sarah, Peter and the hotel clerk), the restaurant host says he is sorry that they have to wait 5 minutes, and you can see that Sarah is obviously way shorter than Aldous. From the front, Sarah comes up to Aldous' eyes, but when they cut to the back, she is almost below his shoulders. Then when they start walking, she steps off a platform of some sort. They seemed to make her taller for just that frame, and then when they are walking throughout the movie, they don't seem to compensate for the difference.
