Season two of Hogan's Heroes finds Sigrid Valdis -- who later became the wife of series star Robert Crane -- making her first appearances as Hilda, curvaceous blonde secretary of dimwitted German prison-camp commandant Col. Klink (Werner Klemperer). Speaking of Klink, his character is far less the martinet and far more the buffoon during the series' second season; the same can be said of his second-in-command Sergeant Schultz (John Banner), whose self-protective "I see NOTHINK! I know NOTHINK!" mantra gets a real workout when he inadvertently accompanies American POW Hogan (Crane) and his fellow Allied espionage agents on a bombing mission! Several episodes stand out this season, beginning with the two-part "A Tiger Hunt in Paris," in which Nita Talbot is introduced in the recurring role of unpredictable Soviet underground agent Marya. Other highlights include "Reverend Kommandant Klink," in which Klink is hoodwinked into performing a marriage ceremony that will secure the loyalty to the Allied cause of a downed French pilot; and "Will the Real Adolf Please Stand Up," wherein series regular Larry Hovis (Sgt. Carter) is permitted to trot out his hilarious -- and devastatingly accurate -- impersonation of Adolf Hitler.
