->"''Don't bite the hand that feeds you''"

If you like your job - or if you [[MoneyDearBoy just like the money you get from doing your job]] - you don't openly badmouth your workplace or your work environment in front of your TargetAudience.

The same applies to actors, directors, producers - everyone involved in a production down to the backstage workers (if they want to be hired for another production).

Rampant (for good reason) in DVDBonusContent and interviews is the fact that almost every person involved talks about what a great production it was, how they all got along great, and how this production is the greatest they have ever worked on. The job doesn't end when the director yells "cut!" - famous people involved in large productions with millions of dollars at stake can't go right home and tell their family and friends what a terrible work environment they are in, and how much they hate their (equally famous) boss and coworkers.

In short, whenever you see someone going on and on and on about how great the production/actors/everything is, they're selling the show regardless if they really like it or not. No matter [[TroubledProduction how troubled the production really was]], it's practically required in their contract, so it's ubiquitous in Hollywood and all related industries. The truth can come out later in a person's CompromisingMemoirs (which may even reignite interest in said production!), but when the production is released, you want to get people excited about it to sell tickets/copies, and that's easier if everyone thinks you had fun making the production.

Like they say: Money talks, and when it talks, it doesn't tell the truth, it says what it's paid to say. And this is just one such example.

!!Notable Instances and Aversions Of This Trope:
* HilariousOuttakes ''never'' show the director or actors getting actually ''angry'' about a scene that isn't working, or visibly frustrated with a fellow actor who keeps flubbing a line, though you know it must happen. Even Orson Welles' notably profane commercial outtakes don't disparage the product: only the quality of the writing.
** In the outtakes for the ''{{Firefly}}'' episode "Objects in Space", NathanFillion is seen yelling "SUMMER!" at SummerGlau for botching her lines at the end of [[TheOner a very long continuous shot]]. But it's all in good fun and turns into an on-set injoke.
* Part of the movie ''Film/GalaxyQuest'' was how the actors had to continue to sell the show despite how they actually felt about it.
-->'''Jason Nesmith''': You WILL go out there.\\
'''Sir Alexander Dane''': I won't and nothing you say will make me.\\
'''Jason Nesmith''': [[SellingTheShow The show must go on]].\\
'''[[ShakespearianActors Sir Alexander Dane]]''': ...Damn you.
* Creator/MeganFox notoriously failed to do this and openly [[GodwinsLaw compared]] Creator/MichaelBay to UsefulNotes/AdolfHitler, single-handedly torpedoing her career almost overnight. As it turned out, it was ''Film/{{Transformers}}'' producer Creator/StevenSpielberg who was personally offended, and not Bay himself. Not really surprising, as Spielberg is Jewish (meaning that he's not likely to brush off Nazi comparisons), and one of the biggest films of his career, ''Film/SchindlersList'', was about a German man who saved several Jews from the Nazi death camps by employing them to work in his factories.
* Likewise, Katherine Heigl got a lot of bad publicity for a ''Variety'' interview where she slammed ''Film/KnockedUp'', her break-out movie, as stereotypically sexist. She may have had a point, but even many people who agreed with her viewed it as an ungrateful betrayal, and the string of (arguably more stereotypical, and certainly much more mediocre) {{romantic comed|y}}ies she made after it caused the HollywoodHypeMachine to turn against her.
* Creator/BillCosby famously told people not to see ''Film/LeonardPart6'', saying it was a terrible movie. That and the flop of ''Film/GhostDad'' probably ensured he'd never have a major film career [[Series/TheCosbyShow outside of television]].
* When Creator/PaulNewman learned that a 1966 re-release of his first film, 1954's ''The Silver Palace'', was planned so as to cash in on his new fame, he took out full-page newspaper ads apologizing for it.
* Creator/RobertPattinson is quite vocal about how much he loathes ''Film/{{Twilight}}'', Creator/StephenieMeyer, and the fans. It's made him hugely popular with ''Twilight''[='=]s {{hatedom}}.
* ''Series/DoctorWho'':
** In [[http://benjamincook.net/writing/doctor-who-magazine/interviews-and-articles/paul-mcgann-daphne-ashbrook/ this interview]] about the [[Recap/DoctorWhoTVMTheTVMovie TV movie]], Creator/{{Paul McGann}} and Creator/DaphneAshbrook have nothing but nice things to say about almost everything... except Eric Roberts, who was apparently standoffish, rude (making personal remarks about [=McGann=] being "effeminate"), and sometimes "amazingly bad".
** Creator/StevenMoffat was in a notorious [[OldShame video]] where he and a bunch of other ''Series/DoctorWho'' Wilderness Years {{BNF}}s got drunk together, in which he said the show was awful and slagged off every actor to have played the Doctor to prove his point that Creator/PeterDavison was the only good Doctor. Even though the show was considered dead for good by that point and he was never likely to work on it, even though he was visibly [[AlcoholInducedStupidity drunk]], even though he's been involved in some amazing ''Who'' stories since then and even though he's repeatedly apologised and insists he was only doing it to {{troll}} Creator/PaulCornell, many fans are unwilling to forgive him for it due in part to the fact that there's little to suggest he wasn't being honest about his feelings, and in part to just how vicious some of his comments were.
** Louise Jameson, who played the Fourth Doctor's companion Leela, insisted to the press that she was quitting the role because she'd felt the character of Leela had been taken as far as she could go, and because she wanted to get back to working in theatre. This was all true, but also was to tactfully avoid mentioning the fact that Tom Baker had been bullying her on-set. Almost twenty years later she declined appearing on a Tom Baker interview for ''Series/ThisIsYourLife'' because he'd hurt her deeply enough that she didn't feel comfortable exchanging harmless WittyBanter with him as if nothing had happened. He did eventually apologise to her and the two have since made up and apparently adore each other. In a DWM feature in the November 2014 issue of Magazine/DoctorWhoMagazine she wrote a 'letter to her past self' about it and assured the young Louise that, as strange as it seems, she loves Tom Baker nowadays, now that he's 'mellowed' and is 'nothing but generous'. Aw.
** Janet Fielding, who played the Fourth and Fifth Doctor companion Tegan Jovanka, went on stage at a 90s ''Doctor Who'' convention and announced that a show that treated female characters as badly as ''Doctor Who'' deserved to have been cancelled. She may have had a point, but remarks like that coming so soon after the cancellation (and trying to talk about feminism to an audience of male nerds) did little to endear it to the fandom at the time.
* The ''TitanAE'' DVD commentary provides at least a partial aversion. DonBluth and Gary Goldman had nothing but good things to say about each other and the others that worked on the film, but they were ''not'' shy about badmouthing Creator/TwentiethCenturyFox and their ExecutiveMeddling that starved their movie of time and money (to the point that they were essentially forced to turn out a half-baked product they weren't happy with). By the time their commentary was recorded the movie's disappointing box office numbers would have [[CreatorKiller spelled doom for their careers]] and Fox Animation Studios as a whole, so they really had nothing to lose.
