Django (1966)

Revealing mistake: When Django exits the saloon after having been in there to drink and have sex with Maria, his boots are already covered with wet mud. His boots should have dry, caked-on mud. This means they did multiple takes of this scene, but they didn't bother to clean off the boots between takes. (00:29:15 - 00:29:40)

Nataniele: If you're a coffin maker... sure did pick a good town to settle, sure did.
