Season five of Hogan's Heroes gets off to a lively start with the episode "Hogan Goes Hollywood," in which American POW Col. Hogan (Bob Crane) and his fellow underground agents sabotage a German propaganda film. It is the first of several secret missions undertaken by Hogan's Heroes, who continue to operate a vast and extremely effective counterespionage operation from their prison barracks, right under the noses of their unwitting (and witless) captors, Col. Klink (Werner Klemperer) and Sgt. Schultz (John Banner). Fifth-season highlights include the return of Kathleen Freeman as Gertrude Linkmeier, the bombastic sister of Klink's superior officer General Burkhalter (Leon Askin). Also making a return appearance is Bernard Fox as the redoubtable British underground operative Col. Crittenden, whose rigid adherence to military protocol -- and his monumental stupidity -- is given quite a workout when he is forced to take over a delicate spy mission from the captured Hogan. Finally, and perhaps inevitably given the familiar "I know NOTHINK!" mantra of Sgt. Schultz, the viewer is treated with an episode titled "At Last--Schultz Knows Something."
