Stars Who’ve Spoiled Their Own Projects: Tom Holland, Mischa Barton, Jason Momoa and More

Giving it all away! Over the years, some actors have made it a tradition to spoil details of their highly anticipated projects before they premiere — while others have done so by accident. Tom Holland revealed so many Marvel secrets after being cast as Spider-Man in 2016 that there were later plans put into place to prevent it from happening again. “The Russo Brothers are like, ‘So you’re just standing here, and you’re fighting this guy and just do whatever,’ and I’m like, ‘OK, who am I fighting?’ And they were like, ‘Well, we can’t tell you because it’s a secret.’ I’m like, ‘OK, so what does he look like?’ And they’re like, ‘Well, we can’t tell you because that would give it away,'" Holland teased during an appearance at ACE Comic Con Phoenix in 2018. "I’m just standing there punching the air for 15 minutes, and when I took the job, I didn’t think that’s what I’d be doing. I’ve gotten used to it now.” Filmmakers Anthony Russo and Joe Russo explained that they had to take drastic measures in order to stop the leaks. “Yeah, Tom Holland does not get the script,” Joe confirmed to IndieWire in April 2019. “Tom Holland gets his lines and that’s it. He doesn’t even know who he’s acting opposite of. We use, like, very vague terms to describe to him what is happening in the scene because he has a very difficult time keeping his mouth shut.” The U.K. native isn't the only one in the Marvel universe who has a bad habit of giving too much away. Mark Ruffalo made headlines in 2018 after he managed to stream the first 20 minutes of Thor: Ragnarok on social media. [jwplayer h2a94s9w-zhNYySv2] "In all fairness, it was in my pocket, and they heard the first 20 minutes. 15? When I knew, first my phone was blowing up and I was getting all these texts and I was like, 'I hope my mom's OK.' But I was like, 'I can't check my phone in the middle of the theater, that's rude, especially in my own movie,'" the Spotlight actor shared on Jimmy Kimmel Live! in April 2018. He added: "Then someone from Disney came up, a woman, and she poked me, and she said, 'Turn off your phone!’ I said, 'What, what?' Your phone is on, turn off your phone!... So, I thought I was going to get fired." Ruffalo, who has portrayed the Hulk since 2012, didn't get fired for the mistake, but he also didn't learn his lesson. The following year, the Captain Marvel star teased what fans could look forward to in Avengers: Endgame — and he gave away more than anticipated. “I don’t know what’s gonna happen. I shot, like, five different endings to this movie. I didn’t even get a whole script to this movie,” he told E! News in May 2019, before adding, “He gets married in this,” in reference to Chris Evans' character, Captain America. Although some took that comment as a joke, Captain America did tie the knot in the 2019 superhero flick after traveling back in time to return the Infinity Stones. He decided to stay in the past so he could be with his love interest, Peggy Carter (Hayley Atwell).

Alan Cumming

The Scottish actor, who portrayed Eli Gold on The Good Wife, couldn’t keep the news of character Will Gardner’s (Josh Charles) eventual death a secret until the episode aired.

“I can’t keep secrets! My worst one, remember in The Good Wife there was a bit when Will got shot and died?” Cumming recalled during a February 2023 appearance on Late Night With Seth Meyers. “It was a big thing. … I was also surprised that no one found out [before the episode aired] because I told everybody I knew. I just couldn’t keep it a secret.”

Penn Badgley

"True story: I originally posted this earlier today at like 9am ET, which it turns out was 2 hrs before it was meant to be PREMIERED by @younetflix YES A WORLD PREMIERE OF A POSTER but anyway I did leak it early, unaware I had done so," the actor wrote via Instagram in December 2022, referring to the poster for season 4. "I thoughtfully captioned it with 'felt cute might delete' and then promptly realized oh I might actually have to delete this."

Badgley added: "So I text the ppl in LA, no one’s awake, so then I just delete it to be safe and *then* thought, for the few people who did see it… it was genius. A rare moment of metaphysical profundity in a press cycle. And I wanted to protect that for them bc the truth is Netflix does not need me posting."

Gaten Matarazzo

After the first installment of Stranger Things season 4 premiered, fans were quick to point out that the Vecna twist sounded familiar. Six years prior, Matarazzo showed his support for one theory that he hoped to see come to life.

"There's this one [theory] in this video and he was saying how other test subjects, besides Eleven, like, one through 10, most of them are dead," the actor, who plays Dustin, shared during AOL's Build series in 2016. "But others were banished to the Upside Down. Like, they couldn't get out."

Salma Hayek

“I remember talking to director [Chloe Zhao] for the first time in a hotel where they [hold Comic-Con],” Hayek admitted about her role in Marvel’s Eternals during an October 2021 appearance on The Graham Norton Show. “You know, I’m Mexican, I talk loud. I start asking her questions, she’s like, ‘Shush,’ and I’m like, ‘What?’”

The Grown Ups actress noted that Zhao was “serious” when she told her: “They can hear us and the script is a secret … Next door! You have to be very careful. Everybody knows that we’re talking about the new Marvel movie [in here], they could be [listening through] the walls.”

Ahead of the 2019 release of Avengers: Endgame, Paltrow revealed that Pepper Potts and Tony Stark (Robert Downey Jr.) would have a daughter in the film.

"Pepper and Tony have had a real long journey together. 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," the Goop founder told the official Avengers: Infinity War Magazine in May 2018. "Their relationship has evolved in all of the ways that great romances evolve."

Jason Momoa

During an appearance at San Diego Comic Con, Momoa couldn't help but break down the final moment of DC Comics’ first Aquaman film.

"In the last frame of this movie, you're going to see him actually become the thing he was destined to be," he told Entertainment Weekly in July 2018. "I think when he was a little boy, he had these powers and he didn't hone them in so this [was the] whole journey of him going to become the king."

Sarah Hyland

“So I don’t read scripts of episodes of Modern Family that I’m not in, so I just found out that my grandpa’s dead along with all of you,” the actress announced via Instagram in January 2020 about Frank Dunphy (Fred Willard). “I still feel special.”

 After fans took issue with Hyland spoiling the episode before they got a chance to see for themselves, she followed up with another message, saying, “Oh, yeah, I guess I should have put a spoiler alert for Grandpa Frank dying, but I was just caught off guard. As his granddaughter, you’d think I’d be invited to the funeral.”

Hugh Jackman

“As soon as I saw the script, I got it,” Jackman told Entertainment Weekly in 2017 about Logan. “Logan is someone who is most scared of intimacy, and so he wants to be alone and do things for himself. The idea that, in the end, he must give his life to save someone else … I thought that was really powerful.”

 At the time, Jackman didn't realize that he heavily hinted at his character's ending.
