Quentin Tarantino launches an Avengers: Endgame style anti-spoiler campaign for his new film, Once Upon a Time in Hollywood. Before it was released a month ago and immediately shattered numerous box office recordsEndgame had some of the most secretive marketing in recent memory. Trailers and TV spots barely scratched the surface of the narrative, revealing as little as humanly possible to preserve the narrative's twists and turns. That proved to be a smart decision, since many of Endgame's biggest moments would not have played as effectively if they were spoiled in footage beforehand.

Similar to last year's #ThanosDemandsYourSilence campaign for Infinity War, Endgame directors Joe and Anthony Russo shared a letter imploring fans to not spoil the endgame, allowing viewers to experience the cinematic event with fresh eyes. Apparently, Tarantino is a fan of this strategy, and now he's implemented it for his upcoming movie.

Ahead of Once Upon a Time in Hollywood's premiere at the 2019 Cannes Film Festival, Tarantino posted a letter (via the Sony Pictures Instagram account) asking Cannes attendees to not reveal any major spoilers after they see the film. Check it out in the space below:

Obviously, Endgame to Once Upon a Time in Hollywood is not exactly an apples-to-apples comparison. The former marked the culmination of this generation's defining blockbuster film saga, which had been built up across 22 films in 11 years. The latter, while a highly-anticipated film in its own right, is a standalone work that appeals to a very different target demographic and won't even be in the same ballpark at the box office. Still, Tarantino's stance is understandable. Regardless of what the film is, nobody wants to go in spoiled. Part of the thrill of watching a movie for the first time is finding out what happens as it goes along. Spoilers are definitely an important topic for Tarantino, as he contemplated shelving The Hateful Eight once the script for the Western leaked.

It's also worth keeping in mind that Once Upon a Time in Hollywood's Cannes screening is more than two months before the film reaches general theaters. So, a majority of the moviegoing public still has a ways to wait before they get to see what Tarantino and company delivered. It would be a shame if instead of experiencing the movie as it was meant to be in the summer, Tarantino fans read about vital plot developments on social media or in early reviews. Hopefully, those who see Once Upon a Time in Hollywood honor Tarantino's request, but viewers who can't make it to Cannes might want to mute certain keywords on Twitter.
