Great in everything I saw him in. I can remember an episode of "Gunsmoke"...he played a villain, him and his 3 sons. He looked pretty old then, maybe mature is a better word. Then there was the nutty General he played on MASH, before he came on as Col. Potter. I liked him best as Col. Potter, though. Dragnet is definitely my second favorite, "Bill Gannon" even came back in the remake, with Dan Akroyd.
