Martin Landau played a loathsome bully perfectly well in "Mr Denton On Doomsday."
He also brought a great deal of class to the outlier "The Jeopardy Room."
And, getting back to "Mr. Denton, when Mr. Denton finally stands up to Landau's character I felt like cheering. That was how convincing Mr. Landau was.
Good actor. I'll miss him.
