When the movie Flying Leathernecks (1951) doesn't come as planned, Radar suggests that they watch "Bonzo Runs For President". But Henry requests "The Thing That Ate The Bronx", saying that he could see that one every night. Both of these movie titles were probably the writers' way of spoofing the type of films that were available at the time since neither appear to ever have been made. The first title refers to the chimp from the Bonzo series running for President which is interesting since in 1980 Ronald Reagan was elected President AND starred in Bedtime for Bonzo (1951).
The actress who plays the Korean woman, Kim, is not in the closing credits.
One of the films Radar mentions is "Bonzo Goes To College". Released in 1952 (and presumable after this episode was set), the film starred Edmund Gwenn and Irene Ryan, among others, and was directed by Fred De Cordova. Gwenn is perhaps best known for portraying Kris Kringle in the original "Miracle On 34th Street" (1947); Irene Ryan is best known for playing 'Granny' on "The Beverly Hillbillies" (1962); and Fred De Cordova went on to produce 1,420 episodes of "The Tonight Show Starring Johnny Carson" from 1970 to 1989.
Corinne Camacho (Lt. Regina Hopkins) and Larry Linville (Maj. Frank Burns) would later go on to appear together in The Rockford Files (1974) episode, "A Deadly Maze" (1977) as husband and wife. They don't share any scenes together in this episode of M*A*S*H.
