I don't know what made me think of W.C. Fields Comedy Collection: International House (1933) - I just wanted to see the six-day indoor bicycle race.
It's about an American, Stuart Erwin, going to the city of Wuhu in China to buy the rights to Dr, Wong's radioscope. He hopes to meet his fiancée Sari Maritza there. But he somehow gets mixed up with Peggy Hopkins Joyce, playing Peggy Hopkins Joyce. That name might not mean much now, but she was a famous man-eater and gold-digger, famous for marrying and fleecing rich men. That sort of gives you an idea about what kind of film this is.
The proprietor of the hotel everyone is staying at (International House of Wuhu) is Franklin Pangborn. The house doctor and his nurse are Burns and Allen. Entertainers at the hotel include Cab Calloway (singing "That Funny Reefer Man"), Rudy Vallee, Sterling Holloway, Baby Rose Marie (later of Dick van Dyke fame), and Col. Stoopnagle and Bud.
About midway through, the famous aviator W.C. Fields drops in (literally) under the impression that he's in Kansas City.
Meanwhile, Dr. Wong is trying to tune in the six-day indoor bicycle race on his radioscope. The idea just tickles me.
On reflection, I may have gotten this mixed up with Never Give a Sucker an Even Break, where Fields falls off the smoking deck of an airplane. Maybe that's next.
