Marvel fans are being warned to stay away from social media after leaked footage from the upcoming "Avengers: Endgame" was found circulating online.

Walt Disney has kept the film shrouded in so much secrecy that even journalists and critics weren't permitted to see the film ahead of its premiere. "Endgame" opens April 26.

Those who have viewed the clip have called it "spoiler heavy." Screen shots, gifs, short clips, and detailed posts about what occurred during the clip are already surfacing on Twitter and Reddit.

Disney did not immediately respond to CNBC's request for comment. Marvel Studios appeared to address the incident Tuesday afternoon with a cryptic tweet featuring the hashtag #DontSpoilTheEndgame and a generic-sounding letter from the film's directors, Joe and Anthony Russo, imploring fans to keep quiet about the film's plot.

Dan Hill, CEO of Hill Impact, a marketing, lobbying and PR firm, said the incident could be an opportunity for Disney to respond in a smart way that keeps people talking, like leaking deleted scenes or bloopers from previous Marvel films.

"I think these are opportunities for companies to show their character in a way that maybe the public isn't used to seeing," he said. "It's an opportunity for Disney, which tends to be very buttoned up, to have some fun."

It is likely that the person behind the leak had clearance to view the footage.

Experts say a leak like this likely won't deter fans from going to see the film on its opening weekend.

"If anything this scandal is only serving to ratchet up the level of conversation related to the film and raising the awareness of it to even higher levels," said Paul Dergarabedian, senior analyst at Comscore.

However, it is a deflating moment for Disney after it has worked so hard to prevent any information about the film getting out early.

"Endgame," the 22nd film in the Marvel Cinematic Universe, is expected to finally give some resolution to the events of "Infinity War," in which half the heroes disappeared into dust. It could also serve as the last film for several of Marvel's most iconic characters.

It's also expected to top a number of box-office records and make a run for one of the highest-grossing film slots.

In its first week of presale tickets, "Endgame" sold nearly twice as many tickets on Atom Tickets as "Aquaman," "Star Wars: The Last Jedi," "Avengers: Infinity War," and "Captain Marvel" combined.

CNBC's Amelia Lucas contributed to this report.

Key Points
  • The Disney-Fox merger supplies Marvel Studios with a new roster of characters as leading men like Robert Downey Jr. (Ironman) and Chris Evans (Captain America) star for the last time in 'Avengers: Endgame.'
  • Ryan Reynolds is a box office draw and Deadpool has performed well in movie theaters, taking in roughly $1.5 billion across two films.
  • But the R-rated vehicle could be a tricky one for Disney to integrate with other Marvel superheroes.
  • Disney CEO Bob Iger has said of content like Deadpool, 'there might be room for more of that,' as long as Disney is not 'confusing the consumer' about 'more traditional Marvel product.'
