Mickey Daniels???
I'm afraid I'll have to dispute two of the entries listed for this movie in the category of "uncredited". The only person I could find as a flunky for Mr. Higgins that could be mistaken as Mickey Daniels was the kid who comes out to find Brooks after he's been clocking the horse, to tell him about the meeting.
He bears slight resemblence to Mickey Daniels but it's not him.
Also, George Chandler is listed as the patient in the wheelchair, but this guy is much too old to be him in 1934.
I wonder if there's documentation to back up some of the bit parts played in some of these movies.
