In his review of Who Framed Roger Rabbit, Roger Ebert labeled the film “a breakthrough in craftsmanship.” He marveled at the way the cartoons changed in size and perspective in each frame. From his raving review, a reader can sense that Ebert left the screening flabbergasted. And with good reason. In the most recent episode of Cinefix’s 7 Things You (Probably) Didn’t Know, the team behind the series gives viewers seven reasons and then some for their eyes to bulge out and tongues to wag in awe, as if Jessica Rabbit had just walked by them. And speaking of Jessica Rabbit: Evidently to avoid accusations of rotoscoping a real woman to to create her, the animators reversed her anatomical movements. That’s why her boobs bounce up instead of down. She really was “just drawn that way.”

As were 82,080 other frames of hand-drawn animation. All in all, 743 people came together to make Roger Rabbit happen, including, in a landmark deal, cartoonists from both Disney and Warner Brothers studios. Had it not been for the peacekeeping efforts of Steven Spielberg, Bugs Bunny and Mickey Mouse would’ve never appeared in the same scene together. All of the other facts mentioned in the video relate to the painstaking lengths animators went to to ensure that the toons in Who Framed Roger Rabbit stopped just short of the unforgiving uncanny valley.
