"L'enchanteur Alcofribas" is certainly NOT one of filmmaker Georges Méliès' best films. While I love the man's films and he was a great innovator, here the story is confusing (I had no idea WHAT was happening until I read the IMDB summary) and the trick photography is sloppy...something rare for his 500+ films.
A prince asks a sorcerer to help him learn who his fiancee should be. While in this cave, all sorts of weird stuff occurs and in the end a lot of demony-ghosty folks appear and chase the prince about for no apparent reason.
Among the many film tricks employed in this film, two stand out because they are so poorly executed. Twice images from one set of footage is super-imposed on the film...but in both cases it's not at all lined up properly and really should have been re-done. But I guess with Georges Méliès, sometimes it was more about quantity versus consistent quality...and this is among the poorest and confusing films I've seen...and I've probably seen close to 200 or more of them.
