Actors Who Couldn't Keep Quiet About Upsetting Plot Twists

No matter how hard studios try to avoid leaks, spoilers from highly anticipated films tend to get out one way or another. Some actors just start going off on tangents during interviews and end up saying something they shouldn't. And with so many fans on social media who are eager to get any scrap of information about an upcoming release, spoilers spread like wildfire these days — once an actor opens their mouth, there's no getting those worms back in the can.

Sometimes, an actor will just get a slap on the wrist for saying too much, but other times, they might face more serious consequences for their mistake. With so many people working on the massive blockbuster productions that tend to draw the biggest crowds, it's actually a wonder that more spoilers don't get out. Here are a few actors who screwed up and spilled the beans on major plot twists before their films came out.

Will Smith - I Am Legend

Will Smith has spent enough time in Hollywood to know that spoiling the ending of a film before it comes out is a surefire way to ruin it for an audience. But in 2007, he did just that at a news conference while talking about his film I Am Legend. As Smith began rambling about the film, co-producer and co-screenwriter Akiva Goldsman realized that he had gone too far, and he yelled, "Don't give away the ending!" But it was too late, and Smith had already crossed the line. The journalists present were instructed not to report on the ending of the film, so thankfully, they were able to do damage control.

Since I Am Legend was based on a novel of the same name that had already been adapted multiple times, Smith might have figured that being loose-lipped about the details wasn't a big deal – after all, plenty of people had already read the book, so there weren't really any secrets to keep, right? Well, not quite. The screenwriters completely changed the ending of the film, so ideally, it was supposed to be a surprise for everyone.

Jiang Wen - Rogue One

With a franchise as huge as Star Wars, spoilers are bound to get out every once in a while. At the 2016 Star Wars Celebration in London, Jiang Wen, who played Baze Malbus in the then-upcoming Rogue One: A Star Wars Story, answered a question about his own character. He started off by saying that he couldn't say much about his own fate, but then he proceeded to tell everyone in attendance that Donnie Yen's character, Chirrut Imwe, was going to die.

Luckily, panel emcee Gwendoline Christie came to the rescue and managed to stop Wen from giving anything else away, interrupting him and saying, "I think we need to leave it there now." While he did stick to his promise about keeping his own character's fate a secret, he did spoil another one. Whoops! It seems like he was so eager to deflect the attention from himself that he said a little too much.

Rachel McAdams - The Time Traveler's Wife

Rachel McAdams starred in the film The Time Traveler's Wife, which was based on the novel of the same name by Audrey Niffenegger. McAdams could perhaps be forgiven for assuming that the target audience for the adaptation was already familiar with the book. Of course, the plot of any film that involves time travel will almost definitely include some trippy twists and turns, and that was the case with The Time Traveler's Wife. But those twists aren't as interesting when you know what's coming in advance — the element of surprise is key.

McAdams began revealing major plot twists during a 2009 interview with John Stewart on The Daily Show. For instance, she caught herself describing the protagonist's journey forward in time to his own death. When she realized she had said too much, she didn't try to backtrack. Instead, it just seemed like she figured she might as well run with it and keep talking. Stewart joked that he still couldn't wait to see the film, but after watching that interview, you really wouldn't need to buy a ticket.

Gwyneth Paltrow - Avengers: Endgame

Gwyneth Paltrow has always had trouble holding back when it comes to spoilers. Throughout her time playing Pepper Potts in the Marvel Cinematic Universe, she has been known to let key details slip before the premieres. Before the release of Avengers: Endgame, she revealed a major detail about Tony Stark and Pepper Potts' lives after the tragic events of Avengers: Infinity War... and in doing so, she gave away a lot more than she probably realized.

In an interview for the official Infinity War magazine, Paltrow was asked about Pepper's relationship with Tony. "Pepper and Tony have had a real long journey together," she answered. "She obviously starts as his dutiful assistant, and then the relationship evolves, and now this decade later they're married, and they have a child." Given the piecemeal way in which these movies are often shot, it's not surprising that Paltrow probably didn't even realize that Infinity War would have the couple only briefly discussing potential parenthood and end with them a galaxy apart, only reunited and with a child after Endgame's time-jump. What is surprising is that the official magazine printed the quote in the first place.

Michael Keaton - Batman (1989)

Michael Keaton dropped the mother of all spoilers while promoting Tim Burton's 1989 Batman film. During an interview with David Letterman, the two started delving into Batman's origin story and his connection with the Joker. In the midst of their conversation, Keaton seemingly forgot that the audience was there for a second, because he got a bit carried away and revealed that the Joker was actually the mysterious man who killed Bruce Wayne's parents years ago. This, of course, was not an element of existing Batman mythology, invented as a plot twist for the '89 film.

Needless to say, this was a shock for both Letterman and his audience, and Keaton quickly followed up with, "I'm kind of blowing the plot here." But by that point, the damage had been done, and the audience was probably a little disappointed. However, the spoiler clearly didn't affect the success of the film, which went on to make $411 million worldwide, revitalize the comic industry, and help define superhero movies as we know them. Unfortunately, the central twist wasn't a huge revelation for the people who caught that interview.

Jason Momoa - Aquaman

For some reason, it seems exceptionally difficult for the casts of superhero films to keep quiet about key plot points. Just look at Jason Momoa's slip up on The Late Late Show with James Corden. While promoting their new film Aquaman, Momoa and his co-ster Yahya Abdul-Maheen II made an appearance on the show, and they let the audience in on a few things they weren't really supposed to know.

Momoa started talking about the relationship between their two characters and had a slip of the tongue. He remarked, "There's a whole emotional scene with him and his father because I kill his dad." Momoa then paused and gasped, knowing he just made a big mistake, and joked that this is why he always has Abdul-Mateen answer the questions. He doesn't trust himself to keep the plots of his films under wraps! Perhaps he'll just direct all questions to a co-star the next time he's doing press to be on the safe side.

Mark Ruffalo - Avengers: Infinity War

The ending of Avengers: Infinity War was gut-wrenching for Marvel fans. When the Mad Titan Thanos snapped his fingers, half of all life in the universe disappeared, including beloved characters like T'Challa, Groot, and Peter Parker. But if you caught a particular Good Morning America interview with Don Cheadle and Mark Ruffalo that aired almost a year before the movie came out, you might have seen it coming.

During their appearance on Good Morning America, Ruffalo started getting hyped up about the upcoming film and announced, "In this next one, ha — everybody dies!" Cheadle was visibly upset afterwards, shaking his head and scolding Ruffalo. It's true that Ruffalo wasn't too specific with this spoiler (he seems to have caught himself specifying that "half" of the characters would die, and tried to cover by going hyperbolic), so it didn't seem too memorable at the time. But some fans probably did start to suspect that depressing finale — there's no doubt that some of them fully expected many of the Avengers to perish. Of course, having some time to steel yourself emotionally might have made it easier to accept your favorite character's demise.

Tom Holland - Avengers: Infinity War

Tom Holland is the undisputed king of Marvel movie spoilers. The actor has dropped so many spoilers during interviews that at this point, it's become a running joke. But Holland is so enthusiastic and endearing that it's hard to feel annoyed at him for his habit of letting spoilers slip.

Before a screening of Avengers: Infinity War in Los Angeles, Holland made an appearance and had an announcement for everyone: "I'm alive!" When the audience seemed confused, Holland's mistake slowly dawned on him — he was under the impression that they had just seen the film and knew his character would die, but it hadn't started yet. This is exactly why Benedict Cumberbatch was seemingly assigned the duty of silencing Holland during interviews. Even that wasn't enough in the end — Cumberbatch was at the screening, but Holland just couldn't help himself.

David Prowse - The Empire Strikes Back

Jiang Wen might have spoiled the fate of one character in Rogue One, but many years before that, David Prowse ruined the biggest plot twist in Star Wars history. When the man behind Darth Vader's mask was interviewed about The Empire Strikes Back in 1978 (two years before it was even released), he openly shared one of the most shocking moments in any of the Star Wars films. This pivotal scene is still regularly quoted today, and no one saw it coming. Well, almost no one.

Prowse was at a fan meet-up when he dropped this bomb regarding Luke Skywalker and Darth Vader's relationship: "Father can't kill son, son can't kill father." Thankfully, his reveal was only printed in a single local newspaper article. Today, that kind of spoiler would go viral in minutes. Clearly, not many people read the original article, because the vast majority of fans were totally caught off guard when they found out that Darth Vader was, indeed, Luke Skywalker's father.

Elizabeth Debicki - Guardians of the Galaxy Vol. 2

Guardians of the Galaxy Vol. 2 introduced some new faces to the franchise, like Elizabeth Debicki's character Ayesha. Though she begins the story as an ally of the Guardians, their amicable relationship just doesn't last. This is one of the most important plot points in the film, but Debicki kind of ruined the surprise for the fans.

"She enlists the Guardians to help her fight a sort of galactical beast... it's all going swimmingly until it all turns very, very sour," Debicki told Gizmodo. "Let's just say it goes from amiable to not-so-amiable quite quickly." It's understandable that Debicki was excited to talk about her character's arc, but in doing so, she gave away quite a bit. To be fair, she didn't get into the nitty gritty details of her character's journey, so there was still plenty for audiences to speculate about before seeing the film.

Tyler Nelson - Indiana Jones and the Kingdom of the Crystal Skull

If you don't recognize the name Tyler Nelson, there's a reason for that: he put a stop to his acting career when it had barely begun. Nelson was cast as an extra in Indiana Jones and the Crystal Skull, and naturally, he was over the moon about the opportunity to be a part of an Indiana Jones film. His involvement got some attention in his hometown, and a local newspaper interviewed him to get the scoop on the film.

But instead of simply sticking to the story of how he ended up on set, he started revealing the entire plot of the film. He might as well have handed the reporter a script. He completely violated his non-disclosure agreement, and as a result, he faced some serious consequences. Once word got back to the studio that Nelson had blabbed, Steven Spielberg's spokesman, Marvin Levy, commented, "Who knows whether that particular person will ever work in this town again?" Nelson was promptly cut from the film, and his mistake cost him a future in acting.
