Trivia: Gary Burghoff as Radar was the only actor who appeared in both the movie and the TV series. [If you want to count just one show as an appearance, then G. Wood, the actor who played General Charlie Hammond from the 325th Evac in the movie, the one with the football team, was also in the pilot episode of the TV show where Hawkeye announces that Father Mulcahy is the winner of the trip to Tokyo with 'the lovely Lt. Dish'. I'm not sure that he appeared in any more episodes, but he did appear in that one. Also, Gary Burghoff was the only actor to play the same role in the movie as well as the series, but there were several other actors appearing in both.]
Trivia: In one of the opening scenes, one of the corpsmen is running from a helicopter while carrying one end of a stretcher and he accidentally slips and falls. The director thought it was an appropriate blunder and decided to leave it in.
