After Star Wars and the successful big-screen Star Trek adventures, it's perhaps not so surprising that Gene Roddenberry managed to convince purse string-wielding studio heads in the 1980s that a Next Generation would be both possible and profitable. But the political climate had changed considerably since the 1960s, the Cold War had wound down, and we were now living in the Age of Greed. To be successful a second time, Star Trek had to change too.
A writer's guide was composed with which to sell and define where the Trek universe was in the 24th Century. The United Federation of Planets was a more appealing ideology to an America keen to see where the Reagan/Gorbachev faceoff was taking them. Starfleet's meritocratic philosophy had always embraced all races and species. Now Earth's utopian history, featuring the abolishment of poverty, was brandished prominently and proudly. The new Enterprise, NCC 1701-D, was no longer a ship of war but an exploration vessel carrying families. The ethical and ethnical flagship also carried a former enemy (the Klingon Worf, played by Michael Dorn), and its Chief Engineer (Geordi LaForge) was blind and black. From every politically correct viewpoint, Paramount executives thought the future looked just swell!
Roddenberry's feminism now contrasted a pilot episode featuring ship's Counsellor Troi (Marina Sirtis) in a mini-skirt with her ongoing inner strengths and also those of Dr. Crusher (Gates McFadden) and the short-lived Tasha Yar (Denise Crosby). The arrival of Whoopi Goldberg in season 2 as mystic barkeep Guinan is a great example of the good the original Trek did for racial groups--Goldberg has stated that she was inspired to become an actress in large part through seeing Nichelle Nichols' Uhura. Her credibility as an actress helped enormously alongside the strong central performances of Patrick Stewart (Captain Picard), Jonathan Frakes (First Officer Will Riker), and Brent Spiner (Data) in defining another wholly believable environment once again populated with well-defined characters. Star Trek, it turned out, did not depend for its success on any single group of actors.
