The Imposter is a 2012 documentary film directed by Bart Layton. It’s about the 1997 case of French Frederic Bourdin, who impersonated Nicholas Barclay, a Texas 13-year old boy who disappeared in 1994. The film has reenacted scenes including interviews with Frederic Bourdin and some members of the Barclay family, as well as real television news footage.
I hadn’t heard about this case before, so when I watched it, I couldn’t believe someone would prey upon a grieving family, not knowing whether their child is still alive or what had happened to him. It’s a pretty messed up story and yet an incredible one.
