Only Two Actors Appeared in Both the First and Last Episodes Alan Alda, who played surgeon Captain Benjamin Franklin "Hawkeye" Pierce, and Loretta Swit, known as the nurse, Major Margaret “Hot Lips” Houlihan, were the only two actors to appear in the first episode as well as the two-hour finale. Alda appeared in all the episodes during the 11 seasons M*A*S*H was aired and was also the director of the finale. Swit appeared in all but 11 of the show's 256 episodes. The television series was a spinoff from the 1970 movie M*A*S*H, which was directed by Robert Altman and starred Donald Sutherland.

A Fire at the Filming Location Was Written Into the Script The Fox Ranch in Malibu Creek State Park, used by 20th Century Fox, was the filming location for a number of famous movies as well as being the set for the M*A*S*H finale. A brush fire occurred at the location, and it was written into the script, extending the finale from its originally slated 90 minutes to two full hours. This extension allowed extra commercials to be run, and since they sold for $450,000 for a 30-second spot, the network made more money than they would have had the fire not happened.

Almost 106 million people watched the two-hour M*A*S*H finale, “Goodbye, Farewell and Amen,” in the United States. It was the most-watched program on television until 2010 when it was finally surpassed by Super Bowl XLIV.
