The upcoming Looney Tunes feature Coyote vs. Acme, in which Wile E. Coyote takes the Acme corporation to court over its notoriously defective products, continues a filmmaking tradition stretching back more than 100 years. The technique of blending animated characters with live-action footage dates to animator Max Fleischer's Out of the Inkwell series (1918–21), in which a cartoon clown would escape his drawing board and roam the real world, while Walt Disney pioneered similar effects in his Alice Comedies (1923–27) and later in Mary Poppins (1964). For Coyote vs. Acme, filmmakers used scale puppets on set to give human actors something to react to, before digitally compositing the final animated characters into the footage — a modern refinement of principles that have remained largely unchanged for a century.
