The Godfather
The Godfather’s horse head scene is so shocking that many people remember it as the film’s defining act of violence, as if the movie pauses to show exactly how the poor animal met its end.

Thankfully, or perhaps disturbingly, the murder itself happens offscreen. We only see the aftermath in the bed, which proves that sometimes the most horrifying thing a film can do is skip the violence and let your brain handle the butchery department.
