Michael Denison steals the show
I just saw this on TCM here in the U.S., and just had to comment that Michael Denison completely steals this movie. He is devilish, handsome, witty, and charming, and has the most riveting and engagingly broad, arch grin on his face the whole time. I couldn't take my eyes (and ears) off of him. His delivery is perfect and he has just the right look for the role. I really wish Denison had been in more major roles in more major motion pictures that are shown in the U.S. He left me wanting a lot more.
I can't say the same about the rest of the cast. Michael Redgrave is too old, tired, and boring; the ladies are stilted and mannered; and Dame Edith is just too way over-the-top for me to endure, including that horrible hooting Victorian upper-class way of pronouncing everything. Can that possibly be more annoying? I suppose this is a regional thing, but as an American, who likes things said efficiently and clearly, I found it unbearable.
On the whole, I liked reading the play much more than viewing this slow-footed movie, with the very very definite exception of watching and listening to Michael Denison as Algy. I could have watched and listened to him for hours.
