SAN DIEGO (AP) ? The hordes of zombies, legions of Stormtroopers, leagues of superheroes and crews of Starfleet officers have already begun crawling, marching, flying and beaming into San Diego for that other big convention this week: Comic-Con International. Outside the sprawling bayside venue, the world premiere of "Star Trek Beyond" is being held Wednesday night at the Embarcadero Marina Park. Comic-Con is expected to draw more than 160,000 fans for high-energy sessions featuring casts and crews from such films and TV shows as "Game of Thrones," ''Star Trek," ''Suicide Squad," ''South Park," ''Teen Wolf," ''Aliens" and "The Walking Dead."
