Very entertaining entry in the Perry Mason series. This is due mainly to the appearance of Ricardo Cortez who brings a whole new persona to the role. Affable and good-natured and with a ready smile, Cortez makes Mason seem easy-going and not dependent on alcohol as was the Warren William interpretation. William almost seemed embarrassed but Cortez is like an old shoe, comfortable in the role. Time and again he manages to come off as sympathetic in thankless roles.
"The Case Of The Black Cat" also has a very imaginative script in its favor, so much so that you won't guess the surprise twist ending. Once you see it you might feel the movie doesn't play fair by introducing hitherto undivulged information, but you will agree it is extremely clever. The cast is comprised of some Hollywood backbenchers but they are a very capable group. This picture is as good as "The Case Of The Howling Dog" which starred Warren William, which I thought was the best of the series. So you could make a pun about cats and dogs - if only I could think of one.
