Avengers: Infinity War was already an epic long superhero movie with a run time of two hours and 29 minutes. However, almost as soon as attention shifted toward the fourth Avengers film, it seemed we were in for an even longer experience. The Russo Brothers said the movie could be three hours or more and rumors continued to circulate that the film was clocking in at Titanic levels of length. Now, it appears that we have final confirmation that Avengers: Endgame will, in fact, just barely break the three hour mark, with an official run time of three hours and two minutes.
The run time was briefly posted by AMC Theaters before being taken down, but Fandango has now posted the exact same length, and with those two reliable sources, we can pretty much call this one a done deal.
The three hour and two minute run time is all the more important because, since we're talking about a Marvel movie, every minute counts. The full run of credits is included in that length, and if this were any other movie fans would likely cut out and save themselves eight or ten minutes by skipping the credits, but with Marvel we all know we'll be hanging around until the very end to see if there's a final scene at the end of all the credits.
Marvel has gotten in the habit of running multiple scenes once the credits start, interspersed throughout. Quite often, the important bits that tease future films now come earlier than the end, but with Avengers: Infinity War the Captain Marvel tease came at the very end, so there's every reason to expect that a scene that either sets up Spider-Man: Far From Home or teases where the Marvel Cinematic Universe will be going in Phase Four will be the very last thing we see.
A three hour run time is no joke. That's a seriously long time to sit and watch a movie. On the one hand, you want to make sure you're properly supplied for such an event, you don't want to get hungry and be distracted by your stomach for the bottom half of the film. On the other hand, you certainly don't want to be called away to the bathroom in the middle of the movie, so you might want to take it easy on the fluids.
Three hour movies are not uncommon but back in the day they used to all include intermissions. I saw the road show version of Quentin Tarantino's The Hateful Eight which included an intermission, and I thought it was actually quite nice to have. I wouldn't be against seeing something like that happen in Avengers: Endgame but that's pretty unlikely. We're all going to need to power through this thing together.
