Very well done, and there were not too many spoilers in there for those who want to still watch it.
I think out of all the characters I enjoyed Peter Lorre's the best. What else could you expect from a man who was in Casablanca and other Humphrey Bogart movies? During his short life he proved to be an amazing actor!
Barry Nelson did a good job for not really knowing what or how he was supposed to act. I am still not too sure how it is that he got out of the bathroom at the end. I did see that he picked something up, I would assume he picked the lock which is pretty easy.
Good movie, I enjoy old Shows like that from back then! It kind of Reminded me of Alfred hitchcock.
