*Our magnanimous sponsor Trope Co.® requires us to display this word.Keep in mind that since this is behind the scenes, any In-Universe examples must be about a behind the scenes thing, such as Breaking the Fourth Wall or dealing with a Show Within a Show. Tropes that are there because the writer had to include them, due to outside factors (even if the writer would have preferred to leave them out). It happens for a number of reasons:
— The "Enforced" box of the image on Playing with a Trope
- Executive Meddling
- Executive Veto (where leaving out a trope would weaken the story)
- Moral Guardians
- A Censorship Bureau or Media Watchdog
- Necessary Weasel (Requirements of the genre. For instance, if you want to do a Police Procedural, you had better include the procedure.)
- Constraints of the medium (which can lead to a Pragmatic Adaptation).
- Budget and time limitations.
Tropes that are often enforced (at least in the circumstances noted):
- 555: Fictional phone numbers and addresses need to avoid corresponding to ones in Real Life.
- Adaptational Modesty is practically mandatory in adaptations that strive to reach a general audience. Even if an actor is comfortable with appearing naked onscreen, extended scenes of full-frontal nudity pretty much guarantee a film an "R" rating, which makes a film much harder to market. Especially mandatory if a character is underage; while putting naked underaged characters in a novel or comic book might fly, it most definitely doesn't in a movie or television series, where (with a few exceptions) they have to be played by real underaged actors.
- Avoid the Dreaded G Rating. It's presumed that any work that can be seen without moral qualms by anyone, regardless of age, is not worth seeing by adults ("children will watch anything"). Since this would cut into profits by scaring off parts of the potential audience, it needs to be avoided.
- Bowdlerise: The enforcers could be Moral Guardians, government requirements, Values Dissonance for different countries, etc.
- The Coconut Effect, because Reality Is Unrealistic.
- Coconut Superpowers, because of budgetary problems during production.
- Dawson Casting can sometimes be necessary for legal reasons. A very common example is to avoid Union regulations and/or actual laws in regards to youth actors.
- Take the film adaptation of The Reader. Michael Kross legally couldn't shoot his sex scenes with Kate Winslet until he had turned 18.
- Game of Thrones takes this even further. In the books, Daenerys Targaryen is 13 when she is married off to Khal Drogo, and eventually becomes pregnant with his child—just as she turns 14. She was aged up significantly to avoid the Moral Guardians, but as the time of her birth is tied to Robert's Rebellion, the rest of the cast had to be aged up as well.
- Flynning for theatrical productions, as realistic swordplay would not only be too dangerous, but also remove the audience's Willing Suspension of Disbelief in having them worry about the actors.
- Merchandise-Driven: Any work that exists to promote or sell a product (such as a line of toys) will be constrained by product availability, turnover, popularity and gimmicks. Transformers is probably the most successful example.
- Our Lawyers Advised This Trope: Legal disclaimers are necessary to stave off litigation.
- Post-Script Season: If a show is renewed, it'll get written for, but the writers then have to work their way out of the constraints of the original story.
- Precision F-Strike: In many movies whose producers had to fight for "PG-13" ratings, since the MPAA's rules on profanity mean that a movie arbitrarily receives an "R" rating if it uses the word "fuck" more than once.
- Product Placement is often the result of Executive Meddling, while some are done with the agreement of the filmmakers. Whatever reason, this trope brings more money to the production, which often covers the costs of filming.
- Rose Tinted Narrative: When fiction deals with the history of some region, it may sometimes need this to get mainstream success in that region. In worse cases, Rose Tinted Narrative will be required for publication.
- The Deep South in the first several decades of film got a lot of rose-tinting.
- Also happens with other works that require the authorization of their subjects—authorized biographies, for instance.
- Under The Hays Code, priests, ministers, and other religious authorities had to be portrayed respectfully without exception. Fittingly, one of the co-authors of the Code's actual text was a Jesuit Catholic priest—and while he acknowledged that not all "ministers of religion" were worthy of respect, mockery of any one of them would (supposedly) encourage sacrilegious attitudes.
- Secondary Character Title: It shows up in plays around the time of William Shakespeare, specifically those that dealt with historical monarchs and rulers. Because of the Elizabethan era's rigid social hierarchy, characters of higher social status had to set themselves apart from the commoners by speaking in verse, and plays always had to be named for the character of the highest social ranking—even if they weren't actually the protagonist.
- Julius Caesar, the protagonist is Brutus.
- Cymbeline, the protagonist is Cymbeline's daughter Imogen.
- Henry IV, the protagonist is the young Prince Hal (who was the protagonist in Henry V).
- Henry VI, Part 1 is really about John Talbot's conflict with Joan of Arc, while the remaining two parts are really about the various nobles vying for power around King Henry VI.
- Hamlet, though fictional, might have had to follow that convention, had Claudius not been clearly a murder, and thus not a rightful king.
- Spiritual Successor: When a legal dispute renders a true sequel impossible.
- Two-Part Trilogy: When a work turns out to be particularly successful, executives often demand two or more followups to cash in on the success of the original, which necessitates writing one story that can be stretched over multiple installments.
- Other times a writer gets an idea for a multi-part story, they usually can't get the later installments greenlit unless the first one turns out to be successful, which necessitates writing a first installment that can stand on its own.
- White Male Lead: Because the entertainment industry feels (rightly or wrongly) that white people won't relate to a minority.
- Writing by the Seat of Your Pants: If a work is designed not be to be planned out in advance, but have the story changes be decided by things like random chance, or letting the audience vote on outcomes.
- Vinesauce Tomodachi Life leaves many events and outcomes to the Random Number God, any number of plot twists and character traits are established with no real foreshadowing (for the most part). Since Vinny is livestreaming the game and can't save scum his way out of certain events, he ends up being just as surprised as the viewers are by them. Essentially, the series writes itself on the fly.
- Others using random numbers include Il castello dei destini incrociati and Inglip.
Works that enforced a specific trope:Film - Live Action
- In the Star Wars universe, Yoda remains an example of Inexplicably Awesome because George Lucas explicitly forbade Expanded Universe writers from exploring his backstory, or revealing anything major about his (still unnamed) species.
- In Who Framed Roger Rabbit, Bugs Bunny and Mickey Mouse and Donald Duck and Daffy Duck are Enforced examples of Those Two Guys. When the production staff at Touchstone Pictures (an alternate label for Disney) went to Warner Bros. for permission to use Looney Tunes characters in their film, Warner Brothers only agreed to let them use the A-listers Bugs and Daffy on the condition that they both receive exactly as much screentime as Mickey and Donald, respectively. The surefire way to honor that agreement was to have both characters share every scene with their Alternate Company Equivalents, with neither character appearing without the other.
