Disney’s Who Framed Roger Rabbit? hit theaters in 1988 and while it wasn’t the first film to merge live action and animation it certainly did so on a level of quality not approached by anyone before or since. Sorry, Cool World.
The movie was directed by Robert Zemeckis, the man responsible for Back to the Future, and most of the movie’s success could be attributed to Jessica Rabbit, a cartoon responsible for ushering many adolescent boys into that awkward stage of sexual awakening.
Regardless, the movie began gesticulating at Disney as far back as 1982 evidenced by this crude pencil test with Roger Rabbit voiced by Paul Reubens, aka Pee-Wee Herman.
