- Sir Not-Appearing-in-This-Trailer: Where a major actor doesn't show up in the trailer.
- Lady Not-Appearing-in-This-Game: The opposite of the above, a character featuring prominently in the promotional materials doesn't really play a significant role.
- Advertised Extra: The guy seems to be a major character, but isn't.
- Billing Displacement: The big-name actor plays a smaller part than they were 'supposed' to get.
- Missing Trailer Scene: Where the trailer includes a scene that's been cut from the film.
- Tonight Someone Kisses: Taking a kiss out of context.
- Covers Always Lie
- Real Trailer, Fake Movie:Someone—most likely fans—has created a very convincing trailer for a movie which is unlikely to ever be released.
- Trailer Spoof: The trailer pretends to be for a different movie.
- Yes, commercials count now. This trailer for Snickers' Super Bowl ad leads you to believe that the guys in it really have Betty White on their team. In the actual commercial she is called "Mike" and is told, "You play like Betty White!" She then eats a Snickers, and after a brief cutaway, she's replaced by a guy, proving that she only appears in the ad to support the tagline: "You're not you when you're hungry." And so does Abe Vigoda.
- In the print ads for Son of Svengoolie, if a film was called "X of Dracula" or "Frankenstein's X" they always ran a picture of Bela Lugosi or Boris Karloff in costume as the title monster, even if they weren't in the film and it wasn't a Universal Horror film.
- Most of the hype for Earth2 focused on that world's versions of the Big Three: Superman, Batman, and Wonder Woman. They're killed off in the first issue.
- When Forever Evil was first anounced, DC billed it as Lex Luthor allying the various villains of the DCU to systematically take down the Justice Leagues & every other costume vigilante.
- The trailer for Turnabout Storm shows Phoenix Wright using his Hot-Blooded attitude to scare and intimidate Fluttershy. In the actual story, however, Fluttershy will only speak to Phoenix, since she thinks he's an actual kind of phoenix. Though that part does manifest in the form of Phoenix having to accuse Fluttershy to buy time.
- In The Prayer Warriors, Chapter 10 of "The Evil Gods Part 2" is titled, ""Piper and Jerry goes to Washington DC to Find out Who the Tractor is and Defeat them Once and for All so they would not terrorized by them ever again for as long as God allows Time to go on For." The Prayer Warriors go to "Washing Dick", but do not identify or defeat the traitor.
- The "previews" for Mass Effect Human Revolution will often have details changed from what actually happens.
- At the end of Shadowchasers Twice Told Tales, the author provides a rather vivid and dramatic "trailer" for Shadowchasers Backwater that he admits should not be taken fully at face-value, claiming it contains many scenes where the contexts are probably either misinterpreted and/or incomplete.
- When Waiting for Godot made its American debut in Miami, its marketing prominently featured stars Bert Lahr (The Cowardly Lion) and Tom Ewell (from The Seven-Year Itch). Posters declared the play to be "the laugh sensation of two continents."
- An egregious example is the trailer for the third Arfenhouse movie. The actual movie turned out to be a few seconds long (not counting credits) and was a Take That to all the creator's fans who were nagging him to deliver on his promise of a sequel, though real sequels were eventually made.
- Parodied by Legendary Frog in the One Ring to Rule Them All: Special Edition, in which a "One Ring 3" Teaser includes shout outs to the movie Speed, the Incredible Hulk, and Charlie's Angels. Lampshaded by Sauron, who asks "Will any of this be in the actual movie?" His goblin assistant, Wayne, tells him that it'll all be cut in post-production.
- The season 7 trailer for Red vs. Blue showed both Church and Tex watching over the Red and Blue teams in Valhalla. Neither actually appears in that season. In fact, according to Word of God, the "original" Church actually died at the end of the last season, so it seems likely Tex did as well.
- The difference here is that Red vs. Blue trailers are more like prelude episodes than actual previews. The season 7 trailer contained no footage from later episodes because it wasn't supposed to. Church and Tex seem to have been inserted into it to encourage Wild Mass Guessing as to what unseen role they may have had in the season.
- This ended up backfiring a bit for the initial episodes of RWBY, as early trailers made it look like a fairy tale-themed Dead Fantasy. The first few episodes turned out to be more gradual and comedic with little fight scenes, causing some disappointment among fans. Rooster Teeth admitted they gave a pretty poor showing with that choice a little around the time of the series debut.
- If you aren't familiar with Sluggy Freelance then the first half of this video would have you convinced that the comic revolves around... Well a relatively minor side character. After that it breaks down into half a dozen tiny trailers not to be entirely trusted, before finally giving up and summarizing the comic in one sentence.
- Not a trailer, but a preview fragment. These 2 panels give the impression that the heroes of Swords and Sausages are going to wake up in bed together, naked, under the same blanket. The full page reveals that Tor was only shirtless and Silver slept fully dressed — her hair partially obscured her vest, which has the same colour as Tor's pants.
- More of a case of Never Trust An End-of-Episode Preview: The end of Chuggaaconroy's semifinal episode of his Let's Play of Pokémon Emerald shows a dramatic reveal of Pokemaniac Steve wanting a rematch, leaving a Cliffhanger for the finale. In the finale, Chugga beats Steve in under half a minute and spends most of the actual episode fighting Steven.
- Inverted by Screen Junkies' Honest Trailers which pick apart plot holes and mock the movies featured.
Dishonest as it may be, you gotta admit that it is kinda funny, too.
