Avengers: Endgame is a bladder-punishing three hours long - here's when you should take that toilet break. As the culmination of a 22 movie arc, it's inevitable that Avengers: Endgame's runtime would be Giant-Man sized. At just over three hours, it's not the longest movie ever, but it's a fairly extended time to sit in a theater without a bathroom break, especially if you've downed an extra large soda as well. Luckily, without giving away any spoilers, we're on hand to tell you the best moment to go, if you desperately need to.
As a direct follow-up to 2018's Avengers: Infinity War, Marvel fans know that Avengers: Endgame is going to be packed full of exciting, funny, fan-pleasing moments from start to finish. And, considering that 11 years and 21 movies have been building towards this, you want to miss as little as possible if you do need to dash to the little boys' or girls' room.
If you absolutely have to pee during Avengers: Endgame (and let's be realistic, if you're taking kids they're more likely to need it), then there are a couple of slower-paced moments in the film where you could dash in and out.
The first bathroom break opportunity in Avengers: Endgame comes about 45 minutes into the movie (timings are not scientifically accurate here, just a guide) when Pepper and Tony have a conversation. It's not so integral to the overall plot of the movie that you'll miss anything significant. So, if you have a squirming kid next to you, or you forgot to go before the movie started, that's the time to go.
The second bathroom break opportunity in Avengers: Endgame is around 1 hour 40 minutes in (again, approximate timing). Tony and Steve are in a two-man set piece apart from the main group. This is a plot essential aspect but it's slower paced than what's preceded and you can easily go to the bathroom without missing anything.
After that point, though, you really don't want to miss anything and should just hold it until the ending. As there is no post-credits to Avengers: Endgame, you can leave after the first round of wonderfully-animated names and know you've not missed anything.
It's pretty easy to see why the Russo brothers need three hours to tell the story of Avengers: Endgame. As the climax of over 10 years of Marvel movies and a cinematic universe which has introduced countless characters and their own individual storylines, this is a process that can't be rushed. Their diligence seems to have paid off, with overwhelmingly positive reviews.
Some audiences, though, have taken issue with the length of Avengers: Endgame, prompting some theaters to have an intermission during screenings. But, really, such a break shouldn't be necessary; if viewers don't want to have to take a pee break, then they shouldn't drink too much, while those that do need to go should be able to sacrifice a minute or two for comfort.
