Leather gloves, killer POV shots, crimson gore, and more red herrings than a fish market — this is the land of giallo, baby. And no film exemplifies the mysterious twists and devilish style of the genre better than Dario Argento's "Deep Red." 

One night, a musician named Marcus witnesses the brutal ax murder of a famous psychic in her apartment. Compelled by the case, Marcus assumes the role of an amateur detective with the help of a feisty reporter. As the pair dig deeper and deeper into the mystery, they find themselves the targets of an unseen killer hell-bent on keeping a dark, festering secret buried at all costs. Accentuated by a throbbing score by the prog-rock group Goblin, "Deep Red" is a series of one astonishing set piece after another. Whether you're an old hat at the genre or a beginner looking to see what giallo has to offer, you cannot go wrong with Argento's masterwork.
