One can read whatever they want into Argento's trademark impressionistic lighting, but at base level his films are very simply a visual treat. Deep Red's sumptuous visuals are further complemented by the film's pulsating prog rock soundtrack, courtesy of Romero favourites Goblin. In the lead role of Marcus, David Hemmings is a suitably wet but watchable civilian-cum-private eye, and proves more than competent at ratcheting up the tension levels, most notably during an extended sequence involving a shiver-inducing animated doll. Deep Red arguably owes a great debt, both thematically and in terms of narrative, to Hitchcock's classic Psycho and further explores the Freudian nightmare of obsession, childhood trauma, repression and ideas of the uncanny. Those even vaguely familiar with the latter half of Psycho will likely find themselves solving Deep Red long before it reveals its final twists, but reaching the end before the film does is perhaps no bad thing given the quality of the ride. The preceding 90 minutes are an honest, gripping and sexily shot joy which looks almost better than perfect in high definition.
