Jamie McCarthy/Getty ImagesIn the trailer for the upcoming CBS All Access series "Star Trek: Picard," the titular captain is facing a new final frontierretirement. Patrick Stewart's Jean-Luc Picard is older, brooding and grounded on land in the clip unveiled Saturday at Comic-Con International in San Diego. "These past few years, I really tried to belong here," Picard says in the trailer, 20 years removed from the events of the series "Star Trek: The Next Generation." At least two stars from previous "Star Trek" series make cameos in the trailer: Jeri Ryan's Borg drone Seven of Nine from "Star Trek: Voyager" and Brent Spiner's Commander Data, whose death capped the film "Star Trek: Nemesis." There's even a quick glimpse of a Borg cube, the vessel for the evil collective that opposed Picard and the crew of the Enterprise.
