File:The choir uk 2 dvd copy copy 4948.jpg

Most convincing choirboy "act" ever.

The thing about actors is that most actors are actors. While they are expected to portray fictional characters engaged in a wide variety of occupations, they rarely have the experience to be truly skilled in everything that the character does in the story. Generally, this isn't a problem. Enough skills can be acquired to fake the job through training from an expert, and for particularly complex tasks a Stunt Double, Talent Double, or Voice Double can be used.

However, on rare occasions, a person, sometimes even a non-actor, will be cast in a role partly because they already have skills from a non-acting work experience or a major hobby that are relevant to the role they are being asked to portray. Examples include both extras and main characters. If the extras are soldiers assigned to the production by the military, it is probably evidence that the film is Backed by the Pentagon. Compare to The Cast Showoff, where scenes are added to an actor's role to give them a chance to show off a talent, and Irony as She Is Cast, when actors are required to display Stylistic Suck in a talent which they are actually quite skilled at.

This trope only refers to someone being cast as a fictional character or as a fictionalized potrayal of a real person. Reality TV, game shows and the like do not count. Neither do non-fictional informative shows hosted by experts in their field, as it is not only normal but pretty much required that, for example, someone that hosts a home improvement show should know something about home improvement.

This is one of the possible methods of using Meta Casting to give added depth to a production.

Fictional examples

Live Action TV

  • Family Matters: In "A Ham Is Born", Carl Winslow moonlights as a security guard at a movie studio where a police drama is being filmed. The movie director is annoyed at Carl's opinion of a film scene until Carl mentions his 20-year experience as a Chicago police officer. After Carl demonstrates the actual procedure for arresting criminals, the impressed director decides to cast Carl Winslow as the new leading protagonist of the film. Ultimately, Carl quits his career as a film star because he, as a married man, refuses to kiss the leading actress, even if it was only part of the movie storyline.
  • On Bones one of the actors in the Film of the Book of one of Dr. Brennan's novels studied to be a scientist, and was hired because the Techno Babble didn't scare him off. This becomes useful when it turns out a real murder had taken place on set, and they needed additional help examining the body.

    • For The Return of the King, The New Zealand Army provided extras for the final battle in front of the Black Gate. Behind the scenes commentary on the DVD's makes note of how good they were as following directions and setting up formations, as how much enthusiasm they brought to the combat scenes.
  • ET the Extraterrestrial - The doctors are real doctors. The commentary mentions that this was because actors wouldn't quite speak as if they had been using the proper terms for years because, well, they hadn't been.
  • Eddie Bunker lived as a criminal and thief many years before becoming a writer. He was later cast as Mr Blue in Reservoir Dogs.

  • In The Best Years of Our Lives, Harold Russell, a man who had lost both hands in World War Two, was cast as a man who had lost both hands in World War Two. He did such a good job he won an Oscar, despite never having acted before.

  • The Lost Skeleton of Cadavra—a parody of 1950's B Movies—references this in a roundabout fashion. Dan Conroy is an actor, but he plays the character of Ranger Brad as though he were an actual park ranger who got talked into playing a role in the movie because he had his own costume.

  • The paramedics attempting to resuscitate Murphy in RoboCop were played by a real-life trauma team. They were allowed to improvise their lines, and on the DVD commentary the writers mention how it turned out better than what they ever could have thought up. One reason it worked so well is that the image of a trauma team working on a dying man in such a calm, emotionless, business-like manner feels incredibly creepy. Most people expect the ER team to act like they do on TV.
  • Many of the military extras in the Transformers series are actual military. In several cases, they didn't even have a script beyond Michael Bay telling them to say and do what they'd do in the situation.

  • A minor example in Airplane!. The screenwriters wrote lines for the two black characters who "only speak Jive". The actors who were cast in the roles pointed out that all the lines were ridiculous and were allowed to improvise their own dialogue.
