Action films are major film genres characterized by non-stop motion, daring stunts, and adventurous heroes. While often financially successful, they are not usually critically acclaimed due to simplistic characters. Some iconic actors of the genre include Sylvester Stallone, Arnold Schwarzenegger, and Bruce Willis. Major film studios like Columbia Pictures and Lionsgate have distributed highly profitable action film franchises such as James Bond, The Expendables, and The Matrix.
