One of those two animated films was "Le Ratapeur de cervelles" ["Brains Repaired"], which is a rehash of "Les Joyeux Microbes" using a mental disease. The transformations here are some of the most remarkable (and non-sensical) of Cohl's career: as two men shake hands in profile, their heads expand into huge crossed bird beaks, filling the screen in a zoom until only their shared eye is seen, which itself expands into a bellows. The other film, "La Revanche des esprits" Spirit's Revenge (now lost), may have been the first film to combine live-action and animation by drawing directly on the live-action film (previous work had used mattes exclusively).
