I do think GILLIGAN probably had one more season in it.
Yeah, had GILLIGAN did another season of 30 episodes, it would've brought the series total up to 128 episodes. Regardless, the show still had ample episodes to air in syndication.
The B&W episodes are sometimes show in their colorized prints. (I don't like that though).
Yes, GILLIGAN (and I'm sure we've discussed it before) was cancelled by CBS in 1967 by Bill Paley who wanted to salvage GUNSMOKE which the network's board had just axed after 12 years. (GUNSMOKE had drooped to Number 35, a good enough rating to keep most shows on the air, but because GUNSMOKE was always expected to be in the Top 10, it got cut). Paley, who liked GUNSMOKE and felt it (obviously) had a longer first-run shelf-life potential than GILLIGAN, uncanceled GUNSMOKE and moved it to early-Monday nights (where it would remain for 8 more years) and, in order to make way, shelved GILLIGAN, despite it still being in the Top 10.
I'm glad he salvaged GUNSMOKE, but Paley should have renewed GILLIGAN for a fourth season, and inserted GILLIGAN into the middle of the '67-'68 season as a mid-season replacement for any new show which quickly flopped.
Any popular series which runs three seasons should probably get a fourth. It's that four-year-itch thing.
And I have to briefly delve back into the B&W-vs-color debate... I
love the different vibe of GILLIGAN's first season (1964-'65) in black-and-white: there is a calm serenity to it (just as there is to BEWITCHED's first season, also 1964-'65) which is 'special'. It should
never have been colorized, as that ruins the B&W ambiance, yet doesn't achieve the "wacky" tone the second season (1965-'66) has which would be in keeping with the general flavor of late-'60s television, a tone that befitted GILLIGAN (and BEWITCHED) which superficial things like colorization doesn't conjure.
But GILLIGAN made the switch (as did ANDY GRIFFITH) at the correct time, the fall of 1965. Any series in B&W that
didn't make the switch to color until a year later, in the fall of 1966 as required by all American primetime series, have a washed-out, anachronistic look.
The B&W vibe from the 1964/65 season is damn near holy. But it looks merely drab if that B&W continues into 1965/66. (Which is why I don't mind so much the colorization of Season 2 of BEWITCHED -- still shot in B&W; yet consider the colorization of Season 1 to be heresy).
It's weird. But it makes some sense. There has always been a lot of talk about where "the line" in the '60s was drawn, as the two halves of the decade were like
two different decades (almost two different centuries). But the calendar year which started out still feeling like the early-'60s (funereal and sacredly pre-apocalyptic) but ended up clearly in evidence that new era had begun (the mad, mod post-apocalyptic late-'60s) was ... 1965.
In TV horror terms, think the original TWILIGHT ZONE versus DARK SHADOWS (although ZONE ended in 1964, and SHADOWS -- a cheapy daytime soap -- was still in B&W through 1967. Which vaguely destroys my point, but some of you get the idea). Or, in terms of cinema, PSYCHO versus ROSEMARY'S BABY (I wanted to use NIGHT OF THE LIVING DEAD as the post-apocalyptic example of late-'60s horror on the big screen, but it was shot in B&W, so my point is lost yet again).
