Gilligan's Island got screwed out of a fourth season because CBS top dog William Paley and his wife couldn't bear to give up their favorite show, Gunsmoke (which had already run for more than a decade by that point). If you ask me, Paley should have been ousted for that little stunt.
I wonder if the Seasoun Four scripts that Sherwood Schwartz wrote still exist somewhere. Perhaps they could be turned into a series of novels (some unused Doctor Who scripts got turned into novels).
