There are few means of gaining experience as a stunt performer prior to actual employment. Involvement in high school or college athletics is helpful, as is acting experience in a school or local theater. As an intern or extra for a film production, there may be opportunities to see stunt people at work. Theme parks and circuses also make much use of stunt performers; some of these places allow visitors to meet the performers after shows.

Stunt performers work on a wide variety of scenes that have the potential for causing serious injury, including car crashes and chases; fist and sword fights; falls from cars, motorcycles, horses, and buildings; airplane and helicopter gags; rides through river rapids; and confrontations with animals, such as in a buffalo stampede. They are hired as actors, but they rarely perform a speaking role. Some stunt performers specialize in one type of stunt.

There are two general types of stunt roles: double and nondescript. The first requires a stunt performer to "double"—to take the place of—a star actor in a dangerous scene. As a double, the stunt performer must portray the character in the same way as the star actor. A nondescript role does not involve replacing another person and is usually an incidental character in a dangerous scene. An example of a nondescript role is a driver in a freeway chase scene.

The idea for a stunt usually begins with the screenwriter. Stunts can make a movie not only exciting, but also profitable. Action films, in fact, make up the majority of box-office hits. The stunts, however, must make sense within the context of the film's story.

Once the stunts are written into the script, it is the job of the director to decide how they will appear on the screen. Directors, especially of large, action-filled movies, often seek the help of a stunt coordinator. Stunt coordinators are individuals who have years of experience performing or coordinating stunts and who know the stunt performer community well. A stunt coordinator can quickly determine if a stunt is feasible and, if so, what is the best and safest way to perform it. The stunt coordinator plans the stunt, oversees the setup and construction of special sets and materials, and either hires or recommends the most qualified stunt performer. Some stunt coordinators also take over the direction of action scenes. Because of this responsibility, many stunt coordinators are members not only of the SAG-AFTRA but also of the Directors Guild of America.

A stunt may last only a few seconds on film but preparations for the stunt can take several hours or even days. Stunt performers work with such departments as props, makeup, wardrobe, and set design. They also work closely with the special effects team to resolve technical problems and ensure safety. The director and the stunt performer must agree on a camera angle that will maximize the effect of the stunt. These preparations can save a considerable amount of production time and money. A carefully planned stunt can often be completed in just one take. More typically, the stunt person will have to perform the stunt several times until the director is satisfied with the performance.

Stunt performers do not have a death wish. They are dedicated professionals who take great precautions to ensure their safety. Air bags, body pads, or cables might be used in a stunt involving a fall or a crash. Stunt performers who must enter a burning building wear special fireproof clothing and protective cream on their the skin. Stunt performers commonly design and build their own protective equipment.

Stunt performers are not only actors but also athletes. Thus, they spend much of their time keeping their bodies in top physical shape and practicing their stunts.
