Avengers: Infinity War held its premiere screening - and it has been confirmed how many post-credits scenes the Marvel Studios movie has. Arguably, the Marvel Cinematic Universe popularized the use of post-credits scenes. When Nick Fury approached Tony Stark about the Avengers Initiative after the Iron Man credits, it laid the foundation for the entirety of the MCU. Now 10 years later, Marvel Studios continues to use mid- and post-credits scenes to tease their upcoming films - and they've become an integral aspect of the moviegoing experience for Marvel releases.

Over the years, Marvel movies have begun to include more than one stinger, one that offers a tease for an upcoming movie and another one that works more as a joke, such as with Thor: Ragnarok and Spider-Man: Homecoming. But Marvel films aren't restricted to two post-credits scenes; Guardians of the Galaxy Vol. 2 had five credits scenes. However, it seems Avengers: Infinity War co-directors Anthony and Joe Russo scaled it back for Marvel Studios' big 10-year anniversary release.

Avengers: Infinity War held its Los Angeles premiere this evening, and started screening for press in other major markets as well, marking the first time it has screened in full for audiences. As such, we know that the movie only contains one post-credits scene - and it's all the way at the end of the credits, just like that first stinger accompanying Iron Man. So Marvel fans will want to stick around to see the button scene after the credits.

The contents of the scene are understandably being kept under wraps along with all the other major spoilers from Avengers: Infinity War. The movie is a major milestone for Marvel Studios, marking not only their 10th anniversary, but the beginning of the end to the narrative they started in Iron Man. Infinity War's main antagonist, Thanos, was introduce in a post-credits scene for The Avengers, and subsequent MCU movies have built to his arrival on Earth. As such, the amount of secrecy around Avengers: Infinity War is unprecedented, even for a Marvel movie, but understandable.

Further, Marvel has started the #ThanosDemandsYourSilence hashtag in an effort to keep fans from spoiling others, with the Russos penning a letter asking moviegoers to respect those who haven't seen it yet. Considering all that hangs in the balance, including the lives of original Avengers like Tony Stark and Steve Rogers, it's no wonder Marvel wants fans to remain unspoiled.

Now, though most Marvel fans know to stay through until the end of the credits, at least the number of button scenes is confirmed and fans know how many stingers to stick around for. For those wondering what exactly that scene entails and how it will affect the MCU, Screen Rant will have a breakdown up once Avengers: Infinity War hits theaters!
