I've really enjoyed all the comments stemming from the new format here.
regarding ROGER RABBIT guest appearances..
Is the painting in this scene a beaver, or could it be MGM's Screwy Squirrel?
A side by side comparison shows it's not Screwy Squirrel. Right gloves, right shape nose but wrong color, wrong cheeks and tail color doesn't match...
Next - is the doorknob here the one from ALICE IN WONDERLAND?
Again, a side-by-side says no. Different mouth, eyes, eyebrows and "hair." Definitely similarities, but no match.
Trivia: Did you know the original ALICE doorknob was voiced by Joe Kearns, the actor who played Mr. Wilson on the original "Dennis The Menace" TV show? It's true!
