“Some actress from TWD sent ricin letters to the Prez? Never heard of her. Anyone know what role she played?” tweeted The Walking Dead’s Glen Mazzara in response to the arrest of Shannon Rogers Guess Richardson, who appeared on his show as “Zombie” and is accused of mailing ricin-laced letters to President Obama and Mayor Bloomberg. “If she played an equivalent part to one she supposedly played on TVD, she was third background from the right. Or something,” responded The Vampire Diaries’ Julie Plec. This just proves that even seasoned Hollywood people sometimes can’t tell when a lowly extra is destined for fame.
