Saving Mr Banks

Being a great fan of Mary Poppins popped to the cinema to see Saving Mr Banks - all about how the relationship between PL Travers ( who wrote the books) and Walt Disney. Terrific film with Emma Thomson in top form .
Unfortunately quick scan of the chimneys tonight shows no sign of a children's nanny armed with an umbrella and carpet bag, nor a dodgy American with an appalling cockney accent .
