Giallo

In Italian cinema, giallo (Italian: [ˈdʒallo]; pl.: gialli; from giallo, lit. 'yellow') is a genre that often contains slasher, thriller, psychological horror, psychological thriller, sexploitation, and, less frequently, supernatural horror elements. This particular style of Italian-produced murder mystery horror-thriller film usually blends the atmosphere and suspense of thriller fiction with elements of horror fiction (such as slasher violence) and eroticism (similar to the French fantastique genre), and it often involves stylized depictions of a mysterious killer whose identity is not revealed until the final act of the film. The genre developed in the mid-to-late 1960s, peaked in popularity during the 1970s, and subsequently declined in commercial mainstream filmmaking over the next few decades, though examples continue to be produced. It was a predecessor to, and had significant influence on, the later slasher film genre.
