One of my all-time favourite films. Celluloid chicken soup. I'd love to read the play.
I think the title speaks for itself here, how can you resist "The Wicked Pigeon Ladies in the Garden"? I loved it, a simple yet magical story, plus there's a moral lesson as well. Pigeons, a leprechaun, moving pictures and time travel always make for a good mix.
A bit dated. I love the wicked ladies, but the moral is a bit heavy-handed, as it often is in the real older kids books. I prefer fake-older books, they're more subversive.
