Originally, when Mrs. Tweedy was cutting off Edwina's head, the shadow on the wall actually depicted the axe coming downward before cutting away. It was further moved back to the current theatrical version where you see the axe going up, but not coming down.
In European versions of the film, instead of the Dreamworks logo, there are the logos for Pathe and Aardman.
In the original version, Mrs. Tweedy angrily berated Mr. Tweedy after the pie machine blew up, to which he pushed the wall down on her. That was cut from the theatrical version, but you can still see him, in the extreme long shot, having just pushed the wall down on her.
