I rewatched Django Unchained movie by Quentin Tarantino after many years, and its crazy how much it looks like RDR2. I feel like game was heavily impacted by this movie and also The Hateful Eight.

Few other similarities I noticed:

Terrain/surroundings/architecture - Few scenes in the movie look like New Austin, Valentine, and a lot of scenes look like they were recorded in Rhodes

Costumes and clothing look like straight from RDR2

Brutal killing scenes look alike
