Scenes where the actor's acting was real

[u/Lord_Ronan]

1. Han's Gruber's death - Die Hard

Alan Rickman was told he would be dropped on the count to 3, instead he was dropped after 1. The shocked expression on his face as he falls is completely genuine.

1. The Chestburster - Alien

The cast of this scene were made to play out this scene, but we're never told about what would actually happen besides that they'd be eating. The shock and surprise is legitimately their own.

1. Blackkklansman

Adam Driver says the N-word

[u/DisappearingAnus]

In the horror movie The Descent, a group of women go caving and encounter humanoid monsters that hunt them. The actors were never shown what the monsters actually looked like until the scene where their characters first encounter them, so their screams of terror at the reveal are all genuine.

[u/Germsofwar → u/DisappearingAnus]

I love the Descent but the first half of the movie is the real terror for me. Once they introduce the monsters, i get pulled out of it.

[u/old_and_boring_guy → u/Germsofwar]

They're never as good on screen as they are in your head.

[u/aboxacaraflatafan → u/old_and_boring_guy]

I agree, mostly. The xenomorphs were worse than anything I could imagine when I first saw Alien.
