After 11 seasons, M.A.S.H. ended its stories of life in a Mobile Army Surgical Hospital with a series finale, "Goodbye, Farewell, and Amen," that became the most watched show in American television history with 106 million viewers, a record that stood until the 2010 Super Bowl.
The half-hour show was always a mix of comedy and drama. But M.A.S.H. behind the scenes wasn't always a smooth success story, with the show's creators, actors, censors, and network often creating drama of their own.
H. Richard Hornberger, under a pseudonym, published his novel MASH: A Novel About Three Army Doctors in 1968. The book, based on Hornberger's 18 months serving as a surgeon attached to a Mobile Army Surgical Hospital (M.A.S.H.) during the Korean conflict, was adapted as a feature film directed by Robert Altman, then turned into a television series.
The character of Benjamin Franklin "Hawkeye" Pierce was a romanticized version of what Hornberger wanted to be like while serving in Korea. "Hawkeye does things I wish I could," Hornberger has reportedly said.
But Hornberger ended up distancing himself from the television series. He was particularly unhappy about Alan Alda's portrayal of Hawkeye. A political conservative, Hornberger thought Alda changed the character into "a liberal," and altered the novel's heroic Hawkeye into a much more flawed human being.
Hornberger also didn't like that the public thought he was against military intervention because of the television series. He told Newsweek that although the show was accurate in its physical portrayal of a M.A.S.H. unit, it "tramples on my memories."
Author Dale Sherman, in his book MASH FAQ: Everything Left to Know About the Best Care Anywhere, suggests Hornberger's novel M*A*S*H Mania, published in 1977, was an attempt by Hornberger to reclaim his original version of Hawkeye Pierce.
When M.A.S.H. was greenlit to be a television series, co-creators Gene Reynolds and Larry Gelbart did not want to make a show that suggested military conflict was fun and games. They wanted to honestly reflect its horrors and the reality of people who lived through it.
So the series showed blood in the operating room, soldiers perishing, and villages getting shelled, as well as more lighthearted moments. In his scripts, Gelbart decided to place serious and comedic storylines side by side; neither he nor Reynolds believed a show had to make the audience laugh at regular intervals.
This led to some clashes with the network, who wanted the show to be lighter. Burt Metcalfe, an executive producer, director, and writer for the show, said that at the end of the first season, a CBS executive claimed the creative team had ruined M.A.S.H. He specifically cited the episode "Sometimes You Hear the Bullet," in which an old friend of Hawkeye's, a reporter, is injured when he goes to visit the front and ends up perishing on the operating table.
Other members of the creative team said Reynolds and Gelbart were prepared to quit if the network didn't let them stick with their vision of the show. Both did eventually leave after the fourth season, although that decision was mainly because of burnout and a desire to work on other projects.
Depite the constant fights between M.A.S.H.'s creative staff and the network, in the entire history of the series, CBS ended up rejecting only one episode.
The episode had nothing to do with how the creators were portraying the Korean conflict; the rejected plot centered instead on the character of Hawkeye Pierce having simultaneous affairs with two nurses.
The cast and crew had just finished filming for the day when a major brush fire swept through the show's California shooting location on October 9, 1982, destroying most of the set. The producers decided to use footage of the fire in the finale; it appears in scenes where the camp staff must leave to escape a fire caused by incendiary devices, and again when they return.
In February 2008 the set was partially re-created at the original Malibu Creek State Park location. When workers reached the original set, all that they found were the rusted-out hulks of an Army jeep and an ambulance. They used old blueprints supplied by 20th Century Fox to rope off locations where the actual tents and other structures had been.
When the Woolsey fire swept through Malibu and the surrounding areas in November 2018, the set was damaged.
