Found in the Internet Archive, D.O.A. of 1950 is a classic film noir movie.
Although I’m not a fan of old movies, this drama mystery was pretty worth it. The basic story is of a person who tries to investigate who murdered him. The story is pretty rich with very good moments of suspense and a nice character build-up. The victim who has received a deadly poison goes out to search for his own killer. During this process there are shootings, lots of detective-style work, romantic scenes and brave escapes.
