Number Seventeen starts out a little hard to follow. It is worth weeding through it. Like so many of the others, Hitchcock particularly focused the drama on the stairs in this film.
One scene shows his peculiar sense of humor. The suspense scene of the couple tied to a stairway railing. The actress remarks to her costar, "It's like the pictures, isn't it?" Just then the railing breaks and they are suspended high above. The audience feels the dangling above death that Hitchcock did so well.

Champagne has some good elements too. It is worth watching if you can get through it's disjointed feel. I particularly like watching the heiress, Betty Balflour, struggle in Paris working as a flower girl at a night club.

On a side note, I have to say that I did like parts of Jamaica Inn. The scenes with Charles Laughton and Maureen O'Hara have something odd but special. It is a weird film for sure. The final scene where Charles Laughton's character goes crazy and climbs the mast is very Hitchcockian.
