Marvel fans should stay off social media if they don’t want to be assaulted by spoilers for the upcoming Avengers: Endgame. Although Disney and Marvel have gone to heroic lengths to prevent any Avengers-related spoilers, it seems that a serious chunk of legit footage leaked online before the film’s premiere.

In a bid to protect fans’ sanity and our own bodily health, we won’t describe what leaked, but according to reports, the footage comprised about five minutes worth of footage from throughout the film, and it appears to divulge several plot points.

Avengers: Endgame premieres April 26th so fans who don’t want to be surprised until then should avoid the gifs, short clips and detail-filled posts on social media.

While Disney has not yet commented, observers say that the person behind the leak must have had clearance to view the footage. Experts say the leak may only drum up interest in the film, instead of suppressing fan turnout.

“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,” Paul Dergarabedian, senior analyst at Comscore, tells CNBC.

Endgame is the 22nd film in the Marvel Cinematic Universe and is expected to resolve events in the Infinity War, in which half of the heroes were destroyed. It may also be the last film for multiple Marvel heroes.
