The theatrical release of Avengers: Infinity War is only days away, which means that the long wait is almost over. But after last night's premiere, some fans have now seen the movie, and Marvel wants to make sure, above all else, that every fan gets an equal opportunity to experience the film the way it was meant to be: spoiler free.

For that reason, Marvel has released a humorous PSA-style video featuring the star-studded cast of Infinity War, to remind fans not to spoil the movie in any way. Robert Downey Jr., Chris Pratt, Mark Ruffalo and a whole lot more actors are on hand to show us how to say no to spoilers.

The video ends with #ThanosDemandsYourSilence, a hashtag that was made famous when directors Joe and Anthony Russo first released a written letter politely asking fans to be respectful to one another, and to not spoil the movie for others.

Now however, even your favorite superheroes have spoken, and they agree with Thanos, the greatest threat they have ever faced -- everyone should keep silent.
