Fedora, Dangerous Stunts

In Hollywood movies of the 1940s, characters often wore a fedora, particularly when playing private detectives, gangsters, or other "tough guy" roles. A trench coat was frequently part of the costume, a notable example being Humphrey Bogart's character in Casablanca . Although the fedora was introduced after the cowboy era (1865-1890), the use of fedoras is common in most TV/movie westerns. The fedora is widely recognized with the characters of The Blues Brothers, Indiana Jones, and Freddy Krueger. The fedora is closely associated with film noir characters. In the case of action/adventure films, such as old "B"-movies, and the Indiana Jones series they inspired, the fedora served the practical purpose of hiding the face sufficiently to allow doubles to perform the more dangerous stunts seamlessly.
