The book in the film

THE movie Paddington2 is the film of the children's book character, the bear Paddington.
           The epicentre of the plot is also a book. 
            We have the series of Paddington books, the film of the books, or a book within the series, and, the crux of the plot, a book. 
            The character comes from a book, and everybody in the film is chasing the villain, who has stolen the book.
            Books in all directions, which is a change from computers, and a reminder that libraries lend books, and shops sell them.
          I hope I've mentioned every book involved.
