One of the TOS adventures that was considered for revisiting was Star Trek: A Piece of the Action
(1968), in which Kirk and Spock discovered that the inhabitants of the planet Iotia had modeled themselves after Chicago mobsters from the 1920s, after reading about the era in an Earth book. The idea was for the Deep Space Nine crew to visit the planet a century later, to find out that they had now modeled themselves after Spock, Kirk and Starfleet, and the planet now looked like 23rd century Earth. The idea was abandoned when screenwriters Ronald D. Moore
and René Echevarria
suggested Star Trek: The Trouble with Tribbles
(1967) instead, since they were huge fans of that one, and could immediately come up with scenes to put the DS9 crew in. See more
