Although I haven't seen every one of his movies, I am reasonably confident to call "Dog Day" the strangest movie Lee Marvin ever appeared in. Why he decided to appear in it, I have no idea, especially since he was still a big star back home in the United States. Fans of Marvin will likely be disappointed by the fact that Marvin doesn't appear in this movie as frequently as he does in his other movies - in fact, he almost becomes a secondary character. The other characters in the movie are a real weird lot, disappearing and reappearing seemingly at random, and acting in random ways when they do appear. Certainly, the movie at first does command your attention because you've likely not seen anything like it before, but it soon becomes tiresome, and you likely won't care what happens at the end when it eventually gets there.
