Case of the Missing Hare (1942)

A travelling magician decides to nail his poster to the side of a tree - but that happens to be the door to "Bugs'" house. The magician makes the mistake of calling him a "dumb bunny" and so, of course - it's war, with the magician's show (and prestidigitation) the subject of sabotage - "Bugs" style! The narrative makes good use of magic circle style trickery and by the end I actually felt a bit sorry for the poor, befuddled, illusionist and he is hamstrung at every turn!
