Actor Seth Gilliam, who plays a priest on the hit TV zombie series “The Walking Dead,” is facing charges in Georgia of drunken driving, speeding and drug possession after he was caught driving 107 miles per hour on a highway not far from where the show is filmed. The 46-year-old actor who plays Father Gabriel Stokes on the popular AMC show, was pulled over early on Sunday morning about 25 miles southwest of Atlanta, where police said they smelled alcohol on his breath and found a marijuana cigarette in his car. He was arrested on charges of drunken driving and misdemeanor marijuana possession, along with speeding and reckless driving. The actor was later released after posting $9,818 bond.
