Other mistake: When walking home from the cinema, Sean says to Bernadette (played by Minnie Driver) "I think your father would be very disappointed to hear that, Minnie". Yes it is Bennie the first time (her character's name), but the second time (ie. the sentence above) is definitely "Minnie".

Continuity mistake: When the girls call 'hello' to the butcher, he is standing in the doorway of his shop holding a cleaver with his assistant behind him. The angle changes and the assistant is now beside him and he has both his hands in his pockets.
Bernadette 'Benny' Hogan: You mustn't mess me about. I know I may look like a rhinoceros, but I've got quite a thin skin really.
