10 MORE Horror Movies You Probably Haven't Seen But Should

10. Girly

Rather than utilising conventional scares, Girly (also known as Mumsy, Nanny, Sonny, & Girly) creates uneasiness through what can best be described as escalating weirdness.

The 1970 horror-comedy opens with unhinged siblings, Sonny and Girly, asking vagrants to join them in a role-playing game. Little do the players know that they'll suffer a swift death if they don't play their roles accordingly (or if the family members simply get bored).

The whimsical setting clashes with the family's deplorable behaviour, making the mind-games and murder profoundly unpredictable. The role-playing scenarios are initially goofy, but become genuinely unnerving, especially when Girly and Sonny implement dead bodies into their sick games.

Each family member is wicked in their own way, but Girly is the standout, thanks to Vanessa Howard's sublime performance. The more she torments her victims, the more innocent she behaves, creating a jarring juxtaposition. When she shows doubt over her family's future, it's hard to tell if she's being authentic or if it's another ploy, ramping up the tension.

Girly is just as creatively creepy as when it debuted, and is well worth checking out if you haven't already.
