The fast-approaching arrival of Avengers: Infinity War in theaters this April has Internet spoilers on full alert. The directors of the latest addition to the Marvel Cinematic Universe recently took to Twitter with a plea that fans resist the urge to spoil the film before others have a chance to see it.

On April 3, Infinity War directors Joe and Anthony Russo posted a tweet which featured the image of a typed letter in the glove of Thanos. The letter discussed the efforts that have been made to keep the plot of the film a secret, and the Russo brothers also stated that they would only be making a minimal amount of footage available for the Infinity War press tour.

The letter concluded with a straightforward request. “Don’t spoil the film for others, the same way you wouldn’t want it spoiled for you.” The message was retweeted by Robert Downey, Jr. who plays Iron Man/Tony Stark in the MCU. Other stars of the film such as Tom Holland have also added their support.

The anticipation for the latest Avenger’s film has reached a fever pitch since it was announced that the release of Infinity War would be moved up to April 2018. The film assembles the largest cast yet and includes Josh Brolin, Scarlett Johansson, Chris Evans, and Chris Pratt. It will premiere in the United States on April 27, 2018. The Russo brothers are hoping to score another hit for the MCU, a production enterprise which shows no signs of slowing down after the massive success of Black Panther and other superhero films. Deadpool 2 is also looming on the horizon.
