Then yesterday, as part of Star Trek Night, a number of fans participated in a pregame costume contest. Before the final judging, J.J. Abrams, director of the upcoming “Star Trek” movie, greeted fans on the video board, which also showed a trailer of the film. Here are the lucky costume contest finalists:
Don’t think ill of the dude in the middle: He’s being introduced to the crowd and soliciting applause as part of the judging. Speaking of which, Paramount Pictures representatives, folks from event sponsor Esurance and Giants relief pitcher Bob Howry picked the winner, based on applause and their own opinions. The lovely green gal (speaking of Earth Day) at right was the lucky choice — she got admission to a special advance screening of “Star Trek” and presumably a wicked case of frostbite. Seriously, it was bitterly cold and windy at the yard last night, and she deserved to win if only for the brave amount of skin she exposed.
