Directors Joe and Anthony Russo and their cast are about to embark on the global press tour for Avengers: Infinity War. The directors, and apparently Thanos (Josh Brolin), are kindly asking those who see the film not to spoil it for anyone else. It’s a reasonable request, even for a Mad Titan.

The press tour begins this week, but no one is actually seeing the film until the world premiere on Monday, April 23, in Los Angeles. Over the next couple weeks, international press, and perhaps even some fans, will only be seeing “a limited amount of selected footage from the film to avoid spoiling the story for future viewers.”

The Russos do not want to give the story away. Most of the actors involved in Avengers: Infinity War did not get the whole script and only saw pages directly related to their characters. The directors say that “only a handful of people know the film’s true plot.” They ask fans and press who see the film not spoil it for others, as not everyone is going to be able to see it at a press screening or at a public screening on opening night.

Disney and Marvel Studios have been extra cautious in how they are handling the publicity tour for Infinity War. They’re using the same playbook Disney has employed for the last three Star Wars films, doing all of the press junkets before anyone actually sees the movie, and then screening the film only days before it hits theaters.

It is an unusual approach for Marvel movies, which often screen and lift review embargoes weeks in advance. Of course, no Marvel movie has ever had spoilers as major as the ones we expect to see in Infinity War, so the extra caution is understandable. We might be predicting character deaths every day, but we don’t want to know which characters are dying until we actually see their demise unfold in the film.

The Russo Brothers have asked nicely and most fans will happily abide, but we’ve all been around long enough to know there are always some who might spoil the fun. Be very careful if you do not want to know what happens in the selected footage that will be screened before the premiere, as descriptions are sure to find their way online.

Once the movie screens at the premiere, you may want to consider an online/social media blackout until you see the film on opening night/weekend. At the very least, stick only with the sources you can trust, knowing they will not spoil the film for you, or anyone else (we will have a non-spoiler review after seeing the film, but that’s it until everyone has a chance to see Infinity War).

That’s really all you can do, short of Thanos using the Infinity Gauntlet to silence all of us like he did his brother, Eros, in the comics.

Avengers: Infinity War is in theaters April 27.
