If its directors are to be believed, Avengers: Infinity War is a movie that’s full to the brim with possible spoilers, and they’re kindly asking that fans don’t spoil what they see until everyone’s had the chance to watch it.

Joe and Anthony Russo tweeted out an image of Thanos’ Infinity Stones-encrusted glove holding down an informal statement of sorts. The statement explains that only a handful of people know Infinity War’s true plot and only a handful of fans will get the opportunity to see 30 minutes of the film before it’s released publicly. The message is clear: No one really knows anything about Infinity War, and the directors want to keep it that way.
