Paddington is a good movie interpretation of the book. They had to add a bit more movie type excitement, and so there are plots and villains that don't exist in the books. The film begins with a much more detailed exploration of Paddington's origins in "Darkest Peru" than Michael Bond provides us with in A Bear Called Paddington. But the film's heart is a sweet, warm movie, about the search for home and family, feeling lost in a new culture, and the love of marmalade, that is enjoyable and funny for movie goers of all ages.
Just in case you missed it.
I did enjoy all the main characters, and always particularly enjoy Matt Lucas on screen. Do watch out for Mrs Brown's shoes. They're rather special. I haven't been able to google what they are, but maybe they are something like these- coincidentally called Louise by John Fluevog. The soundtrack oddly has a rather Cabribean vibe, but perhaps that is close enough to Peru for the movie world.
