Here's my list of Toons for this movie. Note that this list is just for all the Toons that will appear in the new movie that didn't in the first one (although Wikipedia claims that some of them do appear). If you notice any others you want put in or taken out, let me know. Any Toons that could not be added into the first movie for whatever reason will be in this one (the list of Toons from the first movie can be found in here at Wikipedia:
http://en.wikipedia.org/wiki/List_of_Who_Framed_Roger_Rabbit_characters#Cartoon_characters_that_make_cameo_appearances). Here's the list of Toons that will officially appear in this new movie (the names marked with an asterisk (*) are anachronistic in the time period of 1957):

And those are all the new Toons who will appear in the new movie. Once again, if you want to see the list of Toons from the first movie, you can look here:
http://en.wikipedia.org/wiki/List_of_Who_Framed_Roger_Rabbit_characters#Cartoon_characters_that_make_cameo_appearances. Okay, I ended up expanding the list somehow instead of shortening it, but hey, it's set in a later time period, so why not?
