Avengers: Endgame is about 3 hours and 58 seconds and you will need to go to the bathroom at some point... This is what people are saying... However there is one spoiler in the paragraph below so BE AWARE!!! The movie was so good and can't wait to be able to talk about it to the world!
About 55 minutes in
Setting: Japan We see what Hawkeye/Ronin has been up to, but we already knew he was going to be joining up with the gang at some point, so you’re not missing much here other than a rainy fight scene.
About 1 hour and 3 minutes in
Setting:Avengers HQ If you’re sick and tired of hearing about what the Infinity Stones are, go ahead and make a WikiLeak. This scene is mostly comedic and isn’t really telling you anything you don’t already know.
SPOILER* About 1 hour and 10 minutes in
Setting:[Spoiler]Thor and Rocket go somewhere together but there’s a couple minutes of inconsequential banter, so this is a good time to make a quick stop at the urination station.
About 1 hour and 40 minutes in
Setting:New Jersey A car will drive by and cut to a new scene. This is your cue to drop the kids off at the pool.
