Surely it has happened to you more than once. You see a spectacular scene of a movie in a trailer…and then that scene doesn’t make it into the movies. Let’s see how we cheat the trailers of the films.
The trailers of the films that are shown before the premiere have evolved even more than the movies.
The first trailers premiered almost a century ago, consisted of a narrator speaking against a generic background, while the list of actors was displayed. At most you could see a photograph of the film.
30 or 40 years ago these advances were much more subtle than they are now. They tried not to “spoil” the viewer, to the point of not showing an image of the film, or revealing the plot. It is the case of this trailer from Jurassic Park (1993):
But now it is very different. The modern movie trailers are a shameful bottomless pit full of spoilers which can completely ruin the movie for you.
Many go on into eternity, 2:30 or 3 minutes, and reveal key plot points, leaving you looking foolish when you see them. To the point that many people have stopped watching trailers for fear of spoilers.
This is how movie trailers deceive us
but there is another serious problem in the trailers modern: the scenes what later they never appear in the film. You may remember the Infinity War trailer, with the Hulk in Wakanda, running through the jungle with the rest of the heroes, who never appeared in the movie. You can see it in the opening photo.
Many people buy tickets or sign up for a subscription because of what they saw in the trailer… which then never shows up.
Erik Voss, on his YouTube channel The Deep Dive, has dissected over 100 trailers, and discovered four types of trailer hoaxes associated with scenes that later never seen in the movie. You can see it here:
These four types of tricks in the trailers are: scenes that are cut in post-production, scenes with modified special effects, scenes out of context, and what he calls “glamour shots,” which are created for trailers and they are never intended to be in the film.
Some of them are justifiable. Sometimes trailers are shown months in advance, before the final cut of the film, where multiple scenes are dropped.
In other cases, scenes appear out of context, even with modified special effects, to confuse the viewer with the plot, or hide spoilers, and then surprise them in the movie.
But Erik Voss has been able to verify that many films scenes roll specifically designed for trailers, which then do not appear in the film. It’s what he calls “take glam“.
As an example of “glamour take” quote the flight of spider-man and ironman in the trailer of spider man homecomingwhich was supposedly created just for the trailer:

A more controversial example is that of the film yesterdaywhich was advertised with a supposed fragment of the film, where it appeared Ana de Armas.
This scene did not appear in the film. But even 3 weeks after the premiere, when Universal already knew that this scene was not going to be in the film, he kept using it to promote the movie. This is the scene:
Universal was denounced by two viewersfrom what they understood was an intentional deception, and the complaint has been admitted for processing.
It can be understood that some shots from the trailers do not appear in the films, due to last minute cuts. More controversial is when trying to deceive the viewer with scenes shot for promotion, or that are known not to appear in the final cut.
that’s how we cheat the trailers of the films. Although for many, the unforgivable will always be spoilers…
