With only a matter of weeks remaining before ‘Avengers: Infinity War’ hits theaters, directors Anthony and Joe Russo are pleading with fans who see it first to not spoil it for others.

A letter written by Thanos, the film’s main villain, was posted on the Russo brothers’ Twitter account. The letter makes it clear there would be no screenings of the film, even for the press, until after the upcoming Los Angeles premiere. Sections of the film will be shown to press and select screenings will take place after the premiere.

The letter reads:

“Everyone involved with the film has worked incredibly hard the past two years maintaining the highest level of secrecy. Only a handful of people know the film’s true plot.”

For the past two years, fans have been eagerly awaiting the next portion of the ‘Avengers’ series, which promises to be the biggest Marvel film to date, and will bring together all of the characters from the cinematic universe.

Since the release of the movie’s first tailer, eagle eyed fans have been breaking down every single frame, trying to uncover any clue about what will happen in the film, and which character might not make it out alive.

The potential for spoilers is so great that Marvel Studios head Kevin Feige has even said that the title for 2019’s ‘Avengers 4’ is being kept under wraps, because that itself would be a spoiler.

‘Avengers: Infinity War’ hits theaters April 27, here is an official synopsis:

Iron Man, Thor, the Hulk and the rest of the Avengers unite to battle their most powerful enemy yet — the evil Thanos. On a mission to collect all six Infinity Stones, Thanos plans to use the artifacts to inflict his twisted will on reality. The fate of the planet and existence itself has never been more uncertain as everything the Avengers have fought for has led up to this moment.
