Olmos as Picard?
From the Star Trek Wiki’s article “Performers consider for Star Trek roles”:
Edward James Olmos (born 1947) is an Emmy-winning, Academy Award-nominated actor. Leonard Nimoy wanted Olmos to play Kruge in Star Trek III: The Search for Spock, but the role ultimately went to Christopher Lloyd. (Star Trek III: The Search for Spock (Special Edition) special features) A few years later, Olmos was offered the role of Jean-Luc Picard on Star Trek: The Next Generation. However, he had to turn it down as he was busy with other projects.
Wow. I’m not saying I would have preferred this, but maybe I’d like to visit the parallel universe where it happened.
