If you are the UK and close to a branch of FOPP I urge you to spend £3 and buy The Triplets of Belleville (also known as Belleville Rendezvous).
It's a criminally low sum for such a fun and impressive movie. It's a brilliant animation with virtually no script, but it will pull at your heart strings, make you laugh and stun you with some wonderful images. The music is memorable too. I rate it 9/10.
When her grandson is kidnapped during the Tour de France, Madame Souza and her beloved pooch Bruno team up with the Belleville Sisters--an aged song-and-dance team from the days of Fred Astaire--to rescue him.
