Is there a special edition DVD?
I have a documentary somewhere on video tape about the making of the film. What was really interesting was all the weird and wonderful mechanical devices that were used to manipulate the real objects that Roger and the ather cartoon characters handled - like little mechinical robots.
There was also a great story: The actors had to have someone to relate to while filming, as the cartoon characters were not added until a lot later. So a guy dressed up in a really bad rabbit suit and read Roger's lines. Some guys from a rival studio saw this and reported back to their boss "you know, this rabbit film isn't going to be very good!"
