That is what we get at the outset of the film, from prolific British director Michael Winterbottom (A Mighty Heart, Trishna): Plenty of mystery. Much of the questions raised are never quite answered, like who is the man? Is he simply a mercenary, as it appears, traveling from London to Pakistan and into and across India with a slew of false IDs and passports. He may be Jay, the name he uses while speaking to his contact in London, but there's no certainty about that either. Could he be a terrorist as the opening minutes suggest, or just a criminal? Is this a caper, because it later involves stolen gems, or about the complications of relations? That's the sort of chameleon role, one without definition that actor Dev Patel inhabits, in what may be among the most challenging characters he has portrayed. All that is meant, as director Michael Winterbottom said during a roundtable discussion in Toronto, as he’s trying “not to say what the film is about" and "as the film unfolds, it keeps slightly shifting.” What's most surprising about The Wedding Guest is that despite its opacity, it has an organic flow, one that makes for compelling viewing.
