7. The Texas Chain Saw Massacre (1974)

The Texas Chain Saw Massacre shocked audiences with its relentless violence and gritty realism, resulting in bans across several countries, including the UK and parts of Scandinavia. Despite—or because of—its notoriety, the film became a touchstone for the horror genre and a spark for debates about what should be shown on screen.
Its legacy endures as an icon of transgressive cinema, central to ongoing discussions about film ratings, censorship, and the cultural limits of fear. For more, see the British Film Institute.
