The most bizarre story and astounding characters all happen to be true in the engrossing documentary The Imposter. Telling the story of Frederic Bourdin, a 23-year-old French drifter who in 1994 assumed the identity of a missing American teenager, filmmaker Bart Layton mixes unreliable interviews with misdirecting recreations in an attempt to understand why a grieving family would welcome a stranger as their lost son. Bourdin, a wily sprite of a man with an unnerving amount of luck for deception, is just one of half a dozen impossibly unrealistic characters throughout the film. That includes a slick southern P.I. named Charlie Parker who seems to have jumped straight out of a Coen brothers movie. A magic trick of a documentary, The Imposter lulls its audience into laughing at its undeniably weird premise, making it all the more disturbing when the real mysteries start to appear.
