During his apprentice years as a director Alfred Hitchcock took all kinds of assignments, many times directing items that originated on the stage like Juno And The Paycock. Number 17 got an increase of ten in the title, it was originally a play written by Joseph Jefferson Farjeon and when it got to Broadway in 1926 it ran for about a month with a cast you would probably not know. The play itself takes place only in the abandoned house where various folks congregate on a dark night. Several are jewel robbers, one is a detective. Just who is who is not really fully revealed until the end.
Hitchcock really liked trains, he did much better with them in The Lady Vanishes and even better than that in North By Northwest. The British film industry was a lot poorer than the American one, but the fact he's using model electric trains in his high speed climax is rather obvious.
With the exception of Barry Jones who played the off balance nuclear scientist in Seven Days To Noon, no one in the cast will be any kind of familiar to the American audience. The story which is always essential to me is really hard to follow. You might take one or two viewings and you still might not get it all right.
