For no particular reason, I pulled out my blu-ray copy of this film. It holds up amazingly well. If you listen to the commentary and watch the special features, you start to understand what a monstrous undertaking this was and what a huge risk it was for the studio.
It wasn't just inserting animated characters in live action scenes. Roger and the other "toons" pick up and manipulate objects (i.e. Baby Herman's cigar), so they had to build animatronic puppets to hold the objects, which would be superimposed with the toons later.
Direct Robert Zemeckis really praises Bob Hoskins' work, making you believe he sees the crazy toon action that Eddie Valiant sees, and that he's actually picking up something with weight when he grabs Roger by the ears. He was even sent to mime school to perfect this.
Charles Fleischer, the voice of Roger, was physically on set for all the scene with Roger, saying his lines just off camera, and dressed in a rabbit costume! (Lou Hirsch, the voice of Baby Herman apparently elected not to walk around in a diaper).
