Today begins the onslaught of high-profile TV shows on display at Comic-Con, including the debut of AMC’s zombie drama The Walking Dead. While fans of the comic book anxiously wait to see some footage, star Andrew Lincoln is simply anxious to be in front of the Comic-Con crowd. “To be brutally honest, I am [freaking] terrified,” the British actor said in an interview yesterday. “But the other part is it’s so lovely because it’s about people who are deeply enthusiastic about something. And I’m one of these people who believe that everybody needs a hobby to be happy in their life. This is like enthusiasm to the power of enthusiasm. It’s a celebration of a genre, and I admire that. I’m an enthusiast for my work, so I can absolutely key into that. I’m all for new experiences, and I’m sure it will be one heck of a trip.” Other shows on tap for today include The Big Bang Theory, True Blood and the new TNT sci-fi series Falling Skies.
