Jake Gyllenhaal, who put in an engagingly twitchy performance in Villeneuve’s previous feature Prisoners, takes on a dual role here. First, he plays Adam, a bearded, unremarkable history teacher who shuffles through life with the slightly pained expression of a chronic migraine sufferer. Adam becomes obsessed with Anthony, a jobbing actor whom he spots in some sort of breezy romantic comedy called Where There’s A Will There’s A Way. Disturbingly, Anthony looks exactly like Adam (because he’s also played by Gyllenhaal) and, like Adam, lives in Toronto. Adapted from The Double, a 2002 novel by Jose Saramago, Enemy is a murky, inscrutable film – more atmospheric mood piece than conventional thriller. There are vaguely Hitchcockian overtones to some scenes – particularly when Anthony begins to stalk Adam’s girlfriend Mary (Melanie Laurent), his eyes leering predatorily – but Enemy’s more Lost Highway than Dial M For Murder. The Lynchian connections are underlined by a brief appearance from Isabella Rossellini, whose most famous role was arguably Lynch’s classic Blue Velvet. Like Lynch’s more personal films, Enemy functions under its own dream logic. Certain character actions – particularly in the final third – don’t initially make much sense, at least until you start viewing the film as a 90-minute-long nightmare about sexuality and commitment. In The Double, Richard Ayoade’s Gilliam-like adaptation of Dostoyevski’s novel, we saw a much more flamboyant and outgoing Jesse Eisenberg effectively cancel out a quieter, more awkward Jesse Eisenberg. In David Cronenberg’s Dead Ringers, the twins played by Jeremy Irons lived in a state of delicate symbiosis, where the removal of one destroyed the other. In Enemy, one doesn’t cancel the other one out, but rather, they cast each other in a disturbing light, accentuating their paranoia and anxiety. Shot almost exclusively in shades of black and sickly amber, Enemy is punctuated by a trio of arachnid images, which I won’t spoil by describing here. Prowling to an abrupt, startling and possibly even frustrating conclusion, Villeneuve’s film has already been subjected to a number of interpretations, including one theory that the whole thing has something to do with Totalitarianism. In the disc’s scant extras, which amount to a handful of interviews and some behind-the-scenes footage, members of the cast (and Villeneuve himself) talk a bit about their interpretation of the film’s symbolism – Gyllenhaal’s explanation (which, again, I won’t spoil) is among the most plausible. Enemy is out on DVD and Blu-ray on the 9th February in the UK. Follow our Twitter feed for faster news and bad jokes right here. And be our Facebook chum here.
