Character mistake: When Marian is correcting Amaryllis for the girls' poor grammar in saying "can I" instead of "may I" over the cross-hand piece, the girl then asks if she can go play that cross-hand piece and Marian replies, "now you can play your cross-hand piece."
Character mistake: When a flattened Yosemite Sam returns the flattened ball to his wife, there is a theatre across the street that uses the English spelling of "theatre" instead of the American "theater."
