Youtube user Turnmills2000 just uploaded the whole documentary about the making of Who Framed Roger Rabbit, but not the downsized one included in the movie DVD: actually is the original “making of” broadcasted worldwide more than 20 years ago, when the movie was premiered!!
Here it is: Roger Rabbit and the Secrets of Toontown (hosted by Joanna Cassidy, who played Dolores in the movie).
Thanks, Turnmills2000, for uploading this documentary and sharing it with everyone! =3
