Am I the only one who was bothered by the comic book Poirot of Ustinov? He was not the worst Hercule (that distinction belongs to Tony Randal) but he was a yard shy of Finney and a mile south of Suchet. Besides, Dame Agatha was specific regarding the physical appearence of Poirot. Perhaps, the producers of the Ustinov movies felt that, if the public would accept Margaret Rutherford and Angela Lansbury as Jane Marple, they would buy a gargantuan Poirot.
Incidentally, when I said that the Sherlock Holmes stories were sorely lacking in action and humor, I meant that they were poor material for a visual medium.
I am glad that the Nero Wolfe series is getting some recognition. It is the best American made detective show. It has none of the plastic skinned Hollywood glitz of the network fare. It seems to bathe in a Modigliani color scheme (did I spell that right?), not unlike the Warren Beaty "Dick Tracey" film, but more believable.
