The leak has already done the rounds on Reddit, and it's filled with spoilers.
If you're planning to go in cold to 'Avengers: Endgame', you're probably best to stay off the likes of Reddit for the next 11 days.
Mobile phone footage taken from an undisclosed location has made its way online which gives away some major plot points in the upcoming blockbuster - not to mention revealing and spoiling some twists in the movie.
Obviously, since we're such nice people, we're not going to disclose any of what's out there. As you can imagine, fans who have been waiting all year for 'Avengers: Endgame' are now terrified that the spoilers will leak out on the likes of Twitter and some are simply swearing off social media until April 25th.
Disney has not yet released any official statement on the leak, but the original YouTube link to where the footage was posted has now been removed and mirrors are being taken down almost immediately. In other words, you're not going to find this footage easily or at all.
