John Gavin tries hard to be a sort of nebbishy leading man. He's not really very good but it is interesting to see him try.
The trouble here is 90 percent of this show is totally predictable and cliché in every aspect. 3 different "song" scenes just seem like padding and or some attempt to make this episode sort of "musical". The characters are totally stock and all are played pretty flatly. None have any depth to them to involve you in the story. Scott Brady has some fun as a hustling piano player but his whole "You'll come back to be baby." dialog is pretty lame as is all of it. Cardboard characters acted by cardboard actors just can't keep your interested for a hour show.
I recall writer James Bridges in an interview saying he talked to Hitchcock about why he couldn't write a feature film for him and Hitchcock said we don't use our TV writers for features. This may have been a polite way of saying, you're not good enough to write features. I have not seen all of his episodes for Hitch yet, but the few I've seen have been really poorly structured and heavily padded. I'm not knocking his emmy nominated THE JAR episode or AN OPEN WINDOW but some of these others.... Not good.
You really get the set up quickly and then wait forever for anything to happen. There is a nicely staged--mostly with the real actors--fight scene and a few nice dolly shots from director Girard.
Finally there are a few twists in the story in the last few minutes, but one is kind of preposterous and the other just turns the whole thing into a very safe TV show.
I guess if you're a Diana Dors fan you might put up with this more than I could. Sometimes she looks good here sometimes kind of bloated and comes off as a second rate Monroe wanna' be here but that's about all the character calls for anyway.
