Peter Lupus, at the end of the fourth season, had let it be known that he had grown dissatisfied with his salary and the scope of his duties. At the same time, it was known that (incoming producer) Bruce Lansbury had never understood Lupus' function on the show, didn't see the actors appeal, and saw little need for a strongman in the IMF lineup.
Executive Producer Bruce Geller, and Lansbury agreed that Willy would be gradually written out in the fifth season and replaced with a character by the name of Dr. Doug Robert, played by twenty–five–year–old Sam Elliott in his first acting role. It was hoped that the changeover would be gradual enough that viewers wouldn't notice that Willy had been replaced by the end of the season.
The only problem was that Sam Elliott ended up playing the same role of a utility man as Peter Lupus, and, once it became known that Peter was being replaced, there was a letter writing campaign by fans to get Peter reinstated on the series. (It should be noted that Peter Lupus/Willy received the most fan mail out of all the IMF characters on the show.) The big man was asked to return to the series, but Lupus' feelings had been hurt and he considered making his exit permanent. "Everyone talked me out of it," he says. A friend, producer A.C. Lyles had a long talk with him. "Stick with the show," he told Loop. "It's not easy to find another hit. You don't realize while you're doing it that it's not that easy." "So, I'm glad I stayed," Lupus concludes, "though I came very close to walking. And I'm glad that people liked the character so much, because Willy was the most dispensable character."
By the time Peter Lupus returned to "Mission", Executive Producer Bruce Geller had been removed from the series. He drove up to the front gate one day to learn that he had been barred from the lot. "They had two guards escort him to his office," Jonnie Burke recalls. "He took his personal belongings, and they escorted him off the lot."
The character of Doug Roberts would appear in half the episodes of the fifth season and one episode of the sixth season ("Encore", which was a script holdover from the fifth season) before Sam Elliott was let go.
Season Five – Episodes with no ‘Producer’ credit are generally believed to have been produced by Bruce Lansbury. Towards the end of the fifth season Bruce Lansbury was tapped to become Paramount Television’s Vice President in Charge of Creative Affairs. Lansbury and Heath would split production duties until Heath settled into the role of Producer and Barry Crane was promoted to Associate Producer.
