Knock on Wood is for me one of the biggest surprises of the year 1954. I will grant that my expectations were very low before watching Knock on Wood. If a movie can keep me focused for the full movie time, that's really great. What's more, this is definitely the type of movie that you can watch several times and always see something new, interesting. I've been a big fan of such cinema for some time.
