I was a fan of Charlie Chan when the films were first released. I did not realize Sydney was past 70 when he made this movie. There is a lot of humor in the prison scenes. There are a couple of big scenes that come as a surprise for a film that had a shoestring budget. One is the interior of a real prison with the convicts going into their cells in unison. That scene is melded into a stage copy of the same action but slightly more modest. Another scene has a big moving camera set as the cast enters a police lab. There are a lot of familiar faces in the supporting cast. Everyone does a great job with their role. There are some exterior shots of the old cars and trucks which were not that old when the movie was made. This is a good old movie to watch to get a glimpse of what the world was like right after World War II. While watching it you will want to check the ladies hair styles and the interior of the old rooming house and telephones.
