When everyone assembled inAvengers : Endgame , my movie theater lost it !

Movies are magical, especially when you’re laying horizontal in a reclining seat, drowning in popcorn, enjoying a film on the silver screen. While a rowdy audience is normally a definitenoin a movie theater, itispretty magical when something so pivotal happens in the story that everyone erupts into simultaneous applause. Goosebumps!

Reddit threads like this onesay that clapping and cheering in a movie theater is an American thing. (Perhaps we, as a nation, are born with the innate need to cause a scene?)

But these moments are unforgettable, especially when you’re watching a movie for the first time with a bunch of strangers who all react in tandem. In my experience, it happens with sagas where characters are already well-known and conflict has long been brewing — like that scene inAvengers: Endgamewhen it appears hope is lost, but then every superhero in the Marvel-verse arrives.

Whew! So many superheroes assembling caused mass audience applause. Here’s the scene if you need to relive it:

For me, it also happened during this pinnacle moment inHarry Potter and the Deathly Hallows: Part 2, when Harry finally beats Voldemort. That one was a long time coming!

But it’s not just the defeat of a foe — the mere arrival of fan-favorite characters will also do the trick! Like when the OG cast ofStar Warsreturned for the first time duringThe Force Awakens, or when every single Spider-Man (Spider-Men?) arrived on-screen to work together inSpider-Man: No Way Home.
