A first-time cinematic collaboration between the extravagantly imaginative writer Neil Gaiman and the artist-director David McKean (both are intensely revered in the comic-book subculture for their work on the esteemed "Sandman" series, among many other things), the movie has a flickery, handmade quality that recalls such primordial entertainments as George Méliès' 1902 "A Trip to the Moon," and an unrelenting otherworldliness that's indebted to more modern films, like the late Jim Henson's 1986 "Labyrinth." ("MirrorMask" was in fact produced by the puppet masters of the Jim Henson Company.)
