to realize halfway through that the trailer is giving away the entire plot.

And it isn't just a modern problem, either.

Marketing companies have been putting major spoilers in trailers for years.

Let's take a look at some trailers that totally ruined the movie.

And, well, spoilers ahead, obviously.

Last House on the Left

The trailer for 2009's Last House on the Left leaves no surprise unspoiled as it bounces

through the entire script.

In the space of two and a half minutes, we learn that two young women have an unfortunate

run-in with fugitives, who then execute one and leave the other one in a lake.

As they look for a place to hide overnight, the gang ends up at the lake house of the

girl they shot.

If the trailer had stopped there, it would have been pretty good—unfortunately, it

goes on to show the surviving girl making it home, and her parents exacting their revenge

on the criminals…including the literal final scene of the movie.

There's really no point in even watching it now.

You know everything that happens.

Cast Away

It may be one of Tom Hanks' most celebrated roles, but anyone who saw the trailer for

Cast Away promptly had the entire plot spoiled for them.

In the preview, we're shown the plane crash Hanks' character survives and his arrival

on the island where he's stranded.

Standard trailer stuff.

Really makes you wonder if the guy survives, huh?

Well...just keep watching the trailer!

It shows Hanks' character building a raft and writing a note detailing how long he'd

been on the island.

Even worse, it inexplicably tells us that he survives this harrowing journey and makes

it back home.

The Cast Away trailer is also another one of those previews that uses the last shot

of the movie as the last shot of the trailer, so there are literally no surprises left.

Thanks for ruining everything, trailer editors.

"I… have made fire!"

Yup, even that.

Shutter Island

When the first trailer for Shutter Island was released, Paramount Pictures didn't bother

to hide much of the plot.

In fact, the trailer pretty neatly summarized the entire thing.

It becomes evident early on that the disappearance of Rachel Solando is not the real mystery

here, but the existence of an unknown 67th patient at the mental institution and the

quickly accelerating deterioration of the main character's grip on reality.

Thankfully, the trailer left the big, super twisty twist at the end intact for filmgoers,

but that that point, you could pretty much forget about enjoying the ride.

The Sum of All Fears

The trailer for Ben Affleck's debut as Jack Ryan in 2002's The Sum of All Fears is a lesson

in how NOT to do a trailer for a spy film.

This clip sets up the main threat early on: will Affleck and Morgan Freeman be able to

track down the missing Russian scientists before they can build a nuclear bomb and use

it in the U.S.?

That sounds like an intriguing plot, and might have drawn a casual viewer to see the movie.

Unfortunately, the trailer then destroys all the suspenseful build-up by showing the bomb's

detonation.

The rest of the story, where Ryan keeps the President from wrongly retaliating against

Russia, seems like a major letdown after such a big reveal.

Batman v Superman: Dawn of Justice

Naturally, there were several trailers for 2016's mega-movie Batman v Superman: Dawn

of Justice.

But with the second promo trailer, the studio apparently decided to just give away the entire

plot and hope fans were too devoted to the brand to care.

The trailer makes no mystery of most of the critical plot points, with scenes in order

and all the major beats revealed: Lex Luthor introduces Bruce Wayne and Clark Kent, then

manipulates them both to get them to fight.

The two superheroes duke it out for a while, which is in the title, so that's fine.. until

surprise!—here's Doomsday to fight them.

But wait—who appears to save the day?

Why it's Wonder Woman, and the duo becomes a trio—working togethecr to battle the bad

guy and save the world.

Despite all the spoilers, the movie made over $870 million at the worldwide box office,

so apparently the strategy paid off.

Final Destination

All the films in the Final Destination series are pretty bad about putting huge spoilers

in their trailers.

While we know the entire premise of the movies revolves around the demise of people who cheated

fate, spoiling the characters' comeuppance in the trailers pretty much defeats the purpose.

In the trailer for the first Final Destination movie alone, we get to see Tod, Ms. Lewton,

and Billy meet their gruesome fates.

Later installments in the franchise are similarly spoilery, usually revealing the demise of

at least a third of the cast along the way.

Kingsman: The Golden Circle

In 2014's Kingsman: The Secret Service, Colin Firth's character Harry Hart is shot in the

face by Valentine.

It's implied that Hart is out of the picture, with Eggsy taking over his role within the

Kingsman spy organization.

With the first official trailer for The Golden Circle, the Fox marketing team decided to

spoil a huge secret in the final seconds of the trailer:

"Oh my God…

Harry?"

This revelation didn't sit well with director Matthew Vaughn, who said:

"I begged the studio not to reveal it.

Because it's the whole driving force of the first act and if you didn't know that

scene it would've made the whole audience gasp."

Apparently, the marketing guys didn't take the hint, because the second trailer for The

Golden Circle even showed Harry in action, along with a reveal of Julianne Moore's character

as the big bad.

Friday the 13th

Although the 1980 horror film Friday the 13th eventually went on to become a massive box-office

success and spawned an entire franchise, the trailer for the movie definitely didn't do

it any favors.

In typical '80s style, the trailer for Friday the 13th has a voiceover—but this time,

the marketing team at Paramount didn't bother trying to entice audiences with a mysterious

backstory or synopsis.

Instead, they just showed every character's demise while the voiceover counts them.

"One."

Not only does the trailer have no qualms about spoiling every twist in the movie, it also

takes a weird turn—in counting up to the 13 in the title, the trailer implies that

there will be 12 casualties during the film, but there were actually only ten: the nine

victims and Pamela Voorhees herself.

So much for truth in advertising.
