On the very first day of Comic-Con, the network will include an exclusive premiere screening of the highly anticipated new CBS series “Limitless,” a special sneak peek at the newest summer event series, “Zoo,” and a look at what’s ahead for the hit returning series “Scorpion,” “Extant” and “Under The Dome.”

But first, the day will kick off with a special reading of “The Autobiography of James T. Kirk” by Captain Kirk himself, William Shatner.

CBS’ block of panels and screenings is the perfect start to an event that promises to take its fans into a world of fantasy and science fiction.
