Terminator fans were left angry when one of the series' biggest twists, and possibly this year's biggest film twist, was needlessly revealed in a trailer.
Was this the worst 'reveal' in any trailer ever? We've had a look at some of the most unnecessary trailer reveals that ruined films for waiting fans.
WARNING! UNSURPRISINGLY THIS LIST IS FULL OF SPOILERS! YOU HAVE BEEN WARNED!
12. Terminator Genisys
Spoiler: John Connor is sent back as a Terminator
In the second trailer for Terminator: Genisys released in April, the film's huge twist was exposed that a Terminator was sent back disguised as John Connor.
Fans were up-in-arms about the trailer spoiling virtually everything about the plot's storyline, especially the exciting new spin that had been put on the franchise reboot.
Spoiler: Billy Hope's wife is killed
Jake Gyllenhaal plays Billy 'The Great' Hope in the upcoming film in the tried-and-tested plot of 'a boxer fights his way to the top, only to find his life falling apart around him.'
From what we've been given, we already know that Billy's daughter is taken away from him, but the trailer, which reveals virtually all of the film's storyline, shows us the start of Billy's crumbling life when his wife is shot by a fan.
With Jake Gyllenhaal beefing up to play the boxer, we're sure it’s going to be a dramatic and tear-jerking film, but was there any need to provide us with every little detail of the plot?
10. The Double
Spoiler: Richard Gere is Cassius
An action thriller that may have gone under the radar for some in 2011 was The Double starring Richard Gere, Martin Sheen and Topher "Eric Foreman" Grace.
Gere plays Paul Shepherdson, a retired CIA operative who must track down a Soviet assassin named 'Cassius' - believed to be behind a senator's murder - who Shepardson tells everyone that he has killed.
However, the trailer reveals that Gere's character is indeed 'Cassius' himself and had been living a double life as a CIA agent and a Soviet hitman.
9. How to Train Your Dragon 2
Spoiler: Hiccup finds his mother
In the Oscar-nominated sequel to DreamWorks' highest-grossing non-Shrek film, main character Hiccup is captured by a dragon rider after trying to chase down the evil warlord Drago.
Turns out, as shown in the trailer, the dragon rider (voiced by Cate Blanchett) is actually Hiccup's long-lost mother, which ruined a massive mid-film reveal.
Let's hope all those eagerly-awaiting children weren't allowed online to watch the trailers.
Spoiler: Gwyneth Paltrow's character dies
The bleak 2011 thriller about a worldwide epidemic that wipes out thousands of people while the government and CDC try to come up with a cure starred Matt Damon and Gwyneth Paltrow.
Not necessarily a twist, but fairly early on in the film Gwyneth's character - who is patient zero of the contagion - succumbs to the disease.
One of the film's main stars dying towards the beginning of the film would have been a massive surprise, but the trailer gives the game away to audiences who, after seeing the trailer, wouldn't be surprised when Gwyneth bit the dust early on.
7. Terminator 2: Judgment Day
Spoiler: Arnie's Terminator is the good guy
It would seem the Terminator trailers have form when it comes to ruining twists on the film, as Terminator 2 did it all the way back in 1991.
James Cameron went to great lengths to give audiences the impression that Arnie was once again the evil character throughout the film's first third, and this time Robert Patrick's terminator was John Connor's saviour.
That effort was completely negated in the trailer, which outright declared the Arnie had been reprogrammed and sent back by John Connor to protect him.
At least back then the internet wasn't around to make sure every fan had access to plot-ruining film teasers.
6. Children of Men
Spoiler: Clive Owen's character finds the world's only pregnant woman
Alfonso Cuarón brilliant dystopian future thriller where woman are unable to get pregnant and the world has dissolved into chaos.
Clive Owen plays Theo, a former activist who is brought to help save a miraculously pregnant woman to a sanctuary.
The trailer, which could have used a lot more material than what was shown, reveals the pregnant girl, and not only that, gives away aspects of them escaping to The Human Project on the boat.
Still though, there are all those long tracking shots to enjoy.
Spoiler: The prom scene
The legendary horror film, based on Stephen King's novel features the now-iconic prom scene where Carrie had a bucket of pig's blood dumped on her as a prank.
Her resulting rage sets off telekinetic her powers as she kills virtually all of the prom-goers.
The scene is known and loved by film-lovers across the globe, but at the time of its release, audiences were unaware of the film's climax (unless they'd read the novel), so the trailer served to ruin the film's most important scene.
4. Funny People
Spoiler: Adam Sandler's character survives his terminal illness
Coming off the back of the hugely-successful 40-Year-Old Virgin and Knocked Up, Judd Apatow went for the more melodramatic, thought-provoking story of stand-up comic George Simmons who discovers he has terminal leukaemia.
With less than a year to live, George wants to form a genuine friendship with an up-and-coming comedian.
Then, George discovers that his leukaemia is in remission and he gets the all-clear, a moment that doesn't come until the film's third act, but is ruined a minute or so into the trailer.
3. The Lord of the Rings: The Two Towers
Spoiler: Gandalf returns from the dead
After Gandalf is dragged into a chasm by a demon in The Fellowship of the Ring, most thougth that is all we would see from the Istari wizard played by Sir Ian McKellan.
But sure enough, a couple of moments into the trailer for the second film, we discover that the wizard returns as Gandalf the White, more powerful than ever.
Fans of the series, who hadn't read J.R.R. Tolkien's books, found out the wizard's return as Gandalf the White in a trailer, rather than the awesome moment that occurs in The Two Towers.
2. The Island
Spoiler: There is no island and the main characters are clones
Michael Bay's mind-bending thriller didn't go down too well; perhaps he should have stuck to giant transforming robots and massive explosions.
Perhaps another reason was the fact that two massive twists from the film; the fact that main characters Ewan McGregor and Scarlett Johansson are clones, plus sticking Ewan shouting: "there is no island" put pay to the film having any mystery at all.
1. Cast Away
Spoiler: The entire plot
Tom Hanks' performance as Chuck Noland, a FedEx employee who finds himself stranded on a desert island in the South Pacific and makes friends with a volleyball earned the star an Oscar nomination.
In a bizarre and terrible decision by director Robert Zemeckis (of BTTF and Forrest Gump fame) decided to summaries the film in its trailer.
Zemeckis did this on purpose, stating: "we know from studying the marketing of movies, people really want to know exactly every thing that they are going to see before they go see the movie."
So proceeded to provide us with every little detail on the film's plot, including Chuck getting rescued from the desert island after four years - thanks for that.
