Movie Stars in Toons

[jlppr]

is there a complete list of all the shorts from the golden age that portrayed movie stars of its time? i know there were many among the Looney Tunes and if I'm not mistaken Lantz did it in one of his cartoons as well. I just finished watching Mickey's Polo Team for the first time in a very long time and love the fact that there were stars like Laurel and Hardy and two of the Marx brothers. (note, i'm not referring to anything from the Scooby Doo episodes that guest starred a different star each episode)

i would love to see more but i can't remember them all or there names
