I can say this, I am so glad that I never had John Houseman for a professor when I was in college. Whew! the old guy was really intimidating. It was still an enjoyable "thinking mans" show. Houseman was the one who really made it work. He always stood out like a lion in a roomful of kittens. What is so shocking is that before he won his Oscar for Best Supporting Actor for the movie, he had never really acted before. For those of you who are trivia buffs, Houseman was very instrumental in the writing of Citizen Kane. Orson Welles liked to steal all of the credit though. The fact there were different series with different Mister Harts makes it confusing, but still a good show.
