While Bert Wheeler and Robert Woolsey are discussing potential battle plan over the map, a possible embryonic version of "Who's on First?" is spoken between the two.
Bert Wheeler and Robert Woolsey appear separately until the half-way point. This was an experiment by RKO to see if audiences would accept them as solo stars. Because the picture made money, each was given his own vehicle - Wheeler in Too Many Cooks (1931) and Woolsey in Everything's Rosie (1931). Both films flopped, and they were promptly reunited.
During the map sequence, Wheeler says "padlock" and then corrects himself and says "deadlock". It sounds like a genuine slip, but apparently director Cline felt it was worth leaving in.
This was one of about a dozen films that Boris Karloff appeared in during 1931 before his breakthrough role in "Frankenstein" (1931) later that year.
The line "Oh Min !" is a reference to the popular comic strip , The Gumps . It was Andy Gump's catchphrase and would have been understand by contemporary audiences .
