Ah, lovely lovely film. The story is a concoction of Arabian Nights tales: after an encounter with an evil sorcerer, Prince Achmed ends up in the land of spirits, where he falls in love with the princess Peri-Banu and elopes with her. There follows a string of set pieces as the prince and princess head for Baghdad, meeting enemies and friends - amongst them Aladdin - along the way.
It's a simple story, but one that throws in enough little twists to keep your interest.
It may be black and white, but Prince Achmed's animation is worlds away from the likes of Steamboat Willy, and I don't mean that in a bad way. Instead of lifting from contemporary American animation, Prince Achmed is heavily influenced by shadow puppetry.
It may be a trifle clichéd to say that an old film is "still as fresh today as when it was made", but in the case of Prince Achmed it's definitely the case. Viewing it, it's easy to forget that you're watching an eighty year old film; it could just as easily be a modern indie production; only the dialogue captions date it. That's just how unique it is, even today.
