Most of the screenplay is comprised of a married couple arguing over very little which really then puts too much onus on the rest of the screenplay to produce anything worthwhile.
You can tell it was shot in the warmth of the studio as in the mountain scenes everyone is bareheaded – maybe there was something in their contracts about protecting hairdos.
There are some terrible one liners but most of them work. Harpo's performance is the most polished of the brothers and he steals the show (as well as the polish probably).
It was always going to be watchable because of the casting –Georgina Cates is excellent – but the screenplay falters at times and some of the characters are a little overdone even for the stage.
