Unfortunately, they have nothing for 'Opera' and suggested I write to Turner Entertainment, who currently owns the film and production materials.I have yet to hear back from them. I recently wrote to the Motion Picture Academy Library, asking if they had anything in their MGM files. It almost seems as if MGM has deliberately withheld her name, as cast lists with less prominent performers have been released. I've consulted with Marx experts such as Robert Bader and Joe Adamson, and they couldn't help.

I've spent countless hours scouring and other sources, but to no avail.

I later discovered she makes another fleeting appearance earlier in the film as the ship is departing, when Groucho rushes through the crowd to ask if he has time to pay his hotel bill. This was particularly frustrating as she has two lines in the scene, is prominently placed in the foreground of the action, and draws the attention of both Groucho and Chico. except for the lovely manicurist who is being embraced by Groucho in the photo above. Between IMDB and a few other sources, I was quickly able to name them all.
