A cycle of stylish, psychosexually loaded Italian crime films which peaked sometime in the late '70s. The name means "yellow," and refers to the yellow covers of the pulp detective [[{{Literature}} novels]] which were adapted into the first of the films. Gialli are generally plotted as "puzzle" mysteries (with either [[PoliceProcedural police]] or [[AmateurSleuth amateurs]] investigating), but with a heavy admixture of [[HorrorTropes horror]] and thriller elements.

Major directors of gialli include Creator/DarioArgento, Creator/MarioBava, and Creator/LucioFulci.

Many American movies have been influenced by gialli. These include ''Film/BasicInstinct'', ''Film/KillBill, Vol. 2'' (when it isn't being a SpaghettiWestern), the ''Film/{{Hostel}}'' movies, and pretty much anything by Creator/BrianDePalma. {{Slasher Movie}}s have their roots in the giallo sensibility, as well. All quite appropriate, considering the ''considerable'' stylistic influence the genre draws from Creator/AlfredHitchcock--to the point that many have deemed Hitch [[UrExample the unofficial "father"]] [[TropeMaker of Giallo cinema.]]
