Factual error: In surgery Trapper John is singing Frank Sinatra's version of "I got you under my skin". Although it was written in 1936, Sinatra did not release it until 1956, after the Korean War ended. The 1936 version sung by Al Bowlly sounds nothing like the version Trapper John was singing, which was mimicking Sinatra's version.
Revealing mistake: While painting Winchester's portrait, the camera looks across Potter's position. As it does, the picture is totally finished, though Potter acts like he's working on it.Movie Nut
Trivia: After Harry Morgan joined the cast as Col. Sherman T. Potter, the character is shown numerous times painting portraits of the main characters. However, he never painted them. The studio prop master farmed out the work to local talent who was happy for the work. None of those artists have been named.Movie Nut
Character mistake: At the end of the episode, while Col. Potter is in the helicopter asking where they are, the pilot says they are about 10 miles west of Inchon. Col. Potter says this is no good and he tells the chopper pilot to "head west, towards Inchon." If they are already west of Inchon, heading west will take them further from Inchon.
Trivia: Radar is talking with Henry. In this episode, Radar is smoking a cigar, and drinking alcohol, something he did in "Chief Surgeon Who?" But in a later episode, he has trouble when Potter is trying to teach how to smoke a cigar.Movie Nut
