The press tour for “Avengers: Infinity War” is about to begin, and the directors are concerned about spoilers leaking. While footage making its way online is always a concern for Hollywood, the Russo Brothers also don’t want first viewers to divulge secrets to those who haven’t seen the film yet.

The Russo Brothers recently shared a picture of a note signed by them (see below). The note appears to have been written for everyone who gets the opportunity to see the film, or at least parts of it, earlier than everyone else.

The press tour will take the directors across the globe, where they will be interacting with fans. Only selected footage from the movie will be shown during these events to make sure the main storyline will not be revealed so early.

The full movie will be screened only at the Los Angeles premiere. The directors pointed out that the cast and crew have worked hard in the past two years to maintain the secrecy of the plot, and that only a handful of people know the secrets.

The directors requested fans to maintain the same level of secrecy when they see it in the coming months. “Don’t spoil it for others, the same way you wouldn’t want it spoiled for you,” the directors wrote.

“Avengers: Infinity War” will be released on April 25 in Australia. The film will mark the big entry of the main villain Thanos (Josh Brolin) on Earth.
