CONTORTED PASTA

Basil's character has many strengths in itself, but it has in addition an extra one which originates in the relationship between him and his audience. This is that, adult or child, we identify with him. If we are not Basil, we would like to be, and for an hour and a quarter we believe that we are.

[...] Many [Disney features] have a central character whose personality is two-dimensional. It is this character with whom we are intended to identify, and the two-dimensionality is deliberately created so that we can graft onto the character sufficient of our own attributes for the identification to be successful. In The Rescuers, Penny is 'everygirl;' in The Sword in the Stone, Wart is 'everyboy.' In The Great Mouse Detective, however, the character who might might have been expected to take on this role, Olivia, is far from two-dimensional, and it is Basil with whom we are intended to – and do – identify.

Basil is more than just a collection of behaviour patterns. One leaves the cinema feeling that one knows him as a personality – every characteristic rings true. When, for example, Ratigan escapes the palace in his bat-powered dirigible, we may be surprised at the nature of the Heath Robinsonish vehicle which Basil devises for the purposes of giving chase, but we are not surprised that Basil would have been capable of inventing it.
