This was made in 1946 and its the penultimate Marx brothers film as far as I know. Whilst it doesn't stand up to comparison to some of their earlier classics, its still funny and in places a clever film.
Groucho, who was 56 when this was made, plays Ronald Kornblow a replacement manager for the recently murdered previous manager. Actually the plot really doesn't matter very much. What you need to know is that Groucho gets to deliver some classic one-liners:
Ronald Kornblow: You know, I think you're the most beautiful woman in the whole world.
Beatrice Rheiner: [eagerly] Do you really?
Ronald Kornblow: No, but I don't mind lying if it'll get me somewheres.
and perhaps my favourite
Mr. Smythe: Sir, this lady is my wife. You should be ashamed.
Ronald Kornblow: If this lady is your wife, YOU should be ashamed.
Harpo and Chico get to do their inimitable musical turns and theres a lovely set piece with Chico trying to translate Harpo's whistling into words. In fact there are a number of very clever set pieces which certainly make the film worth 3.5 stars.
On the downside some of the support actors were a bit wooden and a couple times the plot was explained to the viewer uneccessarily through the dialog. However overall this was better than I expected.
I strongly recommend purchasing this in the boxed that is available on region 2 which also contains 'A Day At The Races' and 'A Night At The Opera'.
