Update: The Avengers: Infinity War social embargo has lifted. Read the first social reactions HERE!

Marvel's Avengers: Infinity War is nearing its highly-anticipated release at the end of April, but audiences will have to wait a bit longer than is usual for Marvel films for the movie's review embargo to lift, as reviews aren't scheduled to go live until Tuesday, April 24 - the day after Infinity War's world premiere in Los Angeles, CA, and the week of the movie's worldwide release.

The upcoming third Avengers film is helmed by Captain America: The Winter Soldier and Captain America: Civil War directing duo Anthony and Joe Russo, who worked from a script by longtime Marvel screenwriting duo Christopher Markus and Stephen McFeely (The Winter Soldier, Civil War). Infinity War is being hailed as the culmination of an unprecedented cinematic journey, which it rightfully is. The film unites the Earth's Mightiest Heroes with the Guardians of the Galaxy for an ultimate showdown with the Mad Titan Thanos and the Black Order - a conflict that has been in the making ever since Jon Favreau's Iron Man hit theaters in 2008. And now, fans don't have to wait much longer to see it for themselves. But first, the film's social media reactions and reviews will appear online just a few days before the film's release.

The official Avengers: Infinity War social media embargo lifts at 10:30 pm PDT on Monday, April 23, shortly after the film's world premiere in Los Angeles. The review embargo will lift the next day - at 3 pm PDT on Tuesday, April 24. Infinity War then releases worldwide on April 27, with several movie theaters offering late Thursday night showings on April 26, of course.

The level of secrecy surrounding Avengers: Infinity War is unprecedented for Marvel Studios, though not for Disney as a whole, so they are taking every necessary precaution in preventing spoilers from leaking. That's why the embargo date is being held until just two days before it debuts in a handful of countries around the world and three days before it opens everywhere else, including the United States. Marvel typically lifts their review embargoes at least one week before the movies' release. Even the first Black Panther reviews went live 10 days before its global release. The only Marvel movie in recent years that had an embargo lift closer to the release date than Black Panther was Spider-Man: Homecoming, which lifted eight days before its release in 2017.

While this may concern some fans, it's not anything people should be worried about. This is merely an embargo schedule Marvel is borrowing from Lucasfilm - one of their several Disney sister studios. Lucasfilm's last three Star Wars films thus far (all under Disney) have had their review embargoes lift two to three days before those movies hit theaters. It worked out quite well for them, so there's no reason it can't work for Marvel.
