Summary
The MASH TV series, based on the popular novels and movie, did not include the character Duke from the source material.
Duke was excluded from the show for various reasons, including the actor's refusal to reprise the role and concerns about the ensemble being overcrowded. The show addressed this by explaining that Duke had been stationed at the MASH unit years prior to the events of the show and had since moved on to manage a toy store.
CBS' MASH did not include a crucial character found in the novels and Robert Altman's 1970 film adaptation. Richard Hornberger's semi-autobiographical novel, MASH: A Novel About Three Army Doctors, was highly acclaimed and was not only made into a movie but also became a successful 11-season TV series. Led by Alan Alda as Captain Benjamin "Hawkeye" Pierce, the MASH TV show is widely regarded as one of the greatest sitcoms of all time due to its excellent balance of comedy and drama, as well as its enduring relevance even 40 years after its conclusion.
Although all three versions of the story revolve around the 4077th Mobile Army Surgical Hospital during the Korean War, there were differences between them. The novels were detailed and understandably could not be faithfully adapted to the screen. However, the film remained more faithful to the source material when it came to the characters, while the TV show took some creative liberties, particularly due to the departure of several cast members in its early years. Despite these differences, one prominent character from the movie and novels was absent from the CBS sitcom from the very beginning.
Duke Wasn't In The MASH TV Series For Many Reasons
In CBS' MASH, Hawkeye and Trapper John McIntyre formed a notorious duo known for causing chaos and constantly defying authority in the camp. Despite their insubordinate behavior, their exceptional surgical skills always earned them forgiveness. Interestingly, in the MASH novel and film, Hawkeye's original partner-in-crime was Augustus "Duke" Forrest, portrayed by Tom Skerritt in Altman's feature. Surprisingly, Duke was not included in the sitcom adaptation, and there were various reasons behind this decision.
Skerritt declined the offer to reprise his role in the MASH series, indicating that CBS had initially planned to include Forrest. While they could have recast the role, just like they did with the majority of the ensemble, excluding Radar O'Reilly, introducing a third surgeon might have overcrowded the series. With already a large ensemble cast, Hawkeye and Trapper John were already established as captivating leads, thus making a third character unnecessary, especially if he didn't bring anything new to the story. Additionally, Hornberger's refusal to consult on the show made it challenging to accurately portray Duke as intended.
How MASH Explained Duke's Absence
Despite Duke not physically appearing in the MASH show, his absence was explained. It was revealed that he had been stationed at the 4077 MASH unit years before the events of the show. In season 3, episode 8 titled "Life with Father," Hawkeye and Trapper had a conversation with a Korean woman who was searching for someone in their camp. They speculated if she might be looking for Duke, who was referred to as "the brain surgeon who fell a lot" by Trapper. However, Hawkeye informed Trapper that Duke had been gone for two years and had moved on to manage a toy store.
