Jeremy Clarke talks to Richard Williams, Director of Animation on Who Framed Roger Rabbit.

RICHARD WILLIAMS: The initial feeling I had about the picture was that it would look a bit gimmicky. The problem was how to ensure the cartoons didn’t make the live action look false, and that the live action people didn’t make the cartoons look false. They could vitiate each other, cancel each other out. Like a flat Tony the Tiger surrounded by live-action people. You don’t believe he’s real because he’s surrounded by live action, and you don’t believe the live action’s real because there’s a flat cartoon someone has pasted onto the screen, as if on glass.

At my first meeting with Bob Zemeckis (Director) and Steven Spielberg (Executive Producer) we discussed the way these cartoons never interact right with the live-action people. The way to make the thing work, apart from the 3D effect, which we felt we could achieve, was to get the interaction right, because they’re going to be affecting each other physically all the time. Spielberg said, “If the Rabbit sits in a chair, then the chair’s covered in dust and the dust rises from where he sits.” The Rabbit would have a real cup which is rattling all the time. The cartoons and the live-action people would have to be pushing each other, kissing each other, whatever; they are constantly entangled physically, so we used all sorts of puppetry and devices to affect the environment. In fact, in the first hour-and-a-half meeting, which was Bob and I for the first hour, then Steven Spielberg joined us, we had the whole formula worked out, as I recall. Then subsequently we had to do a very elaborate test to prove that we could do it.
