Ann Morriss (Jill Harper), Olin Howland (Ted Slocum), Robert Emmett Keane (Bentley), Erville Alderson (Dr. John Clemens) and Martin Faust (Jake) are in casting call lists/studio records for those roles, but they did not appear in this movie.
I have a marvelous surprise for you...
Henry Conroy: Oh yes?
Henry's Landlady: Your brother's dead!
A drunk (Uncle Henry in disguise) with a jug staggers into the shack where Molly is held captive. He goes over to the table, takes out the cork from the jug and takes a swig. He puts the jug down without putting the cork back in. He staggers a few steps away, then comes back for another drink and the cork has been replaced.
