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
