After discovering that the money they've just stolen from a casino is forged, Lupin and Jigen decide to track down the source of the mysterious 'goat' bills. Their search leads them to the small European country of Cagliostro, ruled by a regent - the scheming Count of Cagliostro - who plans to marry the young heir, Clarisse, in order to legitimize his rulership. Adventure, ninjas and Lupin in his underwear ensue as the whole gang shows up to foil the Count's plans and discover the (hopefully valuable) secret of Castle Cagliostro.
Written and directed by the master, Hayao Miyazaki, this is the quintissential Lupin movie. The suave thief, the young innocent bride, the evil count, and a team of fun cohorts...what more do you need? Even this far back, the art is still beautiful despite the typical funky 70's character design for the main characters (the rest are classic Miyazaki fare, Clarisse looks like a young Nausicaa) and they are all as three dimensional as we'd expect from the great god of animation. Great story, great art, goofy fun and great characters make this one a classic, and something every otaku should own.
Availability: Has been acquired by Manga Entertainment; they've been pushing back the release date for quite awhile. The latest date given was April 2000, but I'd take that with a grain of salt. When it does come out it'll be on DVD and VHS.
