Corrected entry: In the scene in the Wallace and Gromit short film "The Wrong Trousers" where Wallace showed the penguin into Gromit's room, the door opened from the left side. In this movie, Gromit is looking for the rabbit and when he enters his room, the door opens from the right side.
Correction: It is certainly possible that the door and hinges could have been switched to open on the other side at some point between the two stories. The two of them redesign things all the time.
