I need to find that book.
You mean Bruce Geller, right?
Wow, now those are antiheroes! That seems to be a riff on The Dirty Dozen, very different from what we got. I'm not surprised the network didn't go for this version.
Cox's Terry Targo was in the pilot, but as a safe-cracker, not a hit man. And he suffered damage to his hands that, in addition to creating suspense by requiring Rollin to do his job instead, ensured that he would have to retire permanently from his life of crime. I assume the censors insisted on that because the rules of the day required that crime must not be shown to pay.
See, that's what I always figured, that they were a private, off-the-books operation to give the government deniability. A huge contrast with the movies where the IMF is an integral part of the CIA's bureaucracy, pretty much missing the entire point of disavowable operatives.
Of course, the show itself undermined this idea as soon as it started showing the team working hand-in-hand with law enforcement to go after mobsters or other stateside threats, something that was occasionally done as early as the first season, then became the regular focus in seasons 6-7.
The idea that they might occasionally be hired by law enforcement rather than the government is an interesting twist, although it wouldn't have fit with the formula of the Voice on Tape and the Secretary's disavowal in every episode. I guess the Voice could've been the broker assigning their missions, but then not all of the missions would've had the Secretary's oversight.
The first season did pretty much work this way, even more so than this description. Not one cast member appeared in all 28 episodes, because there was one that Briggs was written out of during the dispute with Steven Hill. Dan supervised in 27 episodes and was on the mission in 20. Rollin was in 26 episodes, Barney 25, Cinnamon 24, and Willy only 21. Early on, the guest agents tended to be fairly prominent actors/characters (Wally Cox, Albert Paulsen, Mary Ann Mobley), but became smaller supporting players as the season went on, the main exception being Eartha Kitt in the penultimate episode. The full five members of the main team are present in 15 episodes, and the greatest variation in team size and composition is toward the middle of the season. There are a few four-handers with guest agents, several three-handers, a couple of episodes with only two team members (Rollin and Cinnamon in "A Spool There Was," with offscreen help from Barney, and Rollin and Barney in "The Reluctant Dragon"), and one, "Elena," that's a solo mission for Rollin, albeit with the help of a guest character.
No, Rollin was effectively a regular throughout the whole season, well before the problems with Hill started. The only episodes he wasn't in were numbers 12 and 14 in broadcast order. But once the problems with Hill began, Rollin was upgraded to the de facto series lead. He was always the central player on the missions where Briggs was not on the field team and appeared only in the initial briefing. And Rollin ran the whole mission in the episode that Briggs was written out of completely.
I believe they offered Landau a promotion to lead in season 2, but he didn't want to commit to more than one season at a time, so they brought in Peter Graves instead.
Hunh. I always figured Phelps was meant to be the same as Briggs, a retired intelligence agent. (The Voice on Tape in the pilot said "Welcome back" to Briggs, implying he'd left the CIA and been brought back into the game unofficially to lead the IMF.)
And... oh, man... Phelps was an airline pilot? That's something that plays very, very differently in the wake of Airplane! Oh, man.
