From Frank Abagnale in "Catch Me If You Can" to "The Return of Martin Guerre" to "The Music Man," we are entertained and amused by stories of impostors.
We can also be incredibly, deeply creeped out by them. The more you know of these stories, the more you realize that you might be fooled by somebody really good, especially if you had some reason for wanting the false story to be true. And, beyond that, there's the sense that identity may be more fluid than we like to think. Some the stories you'll hear on this show involve people who got so deep into their fake roles that they really did appear to leave their old identities behind. With a heavily publicized documentary about a young impostor coming to a theater near you, we decided to probe that story and some others like it, from the 19th century to the 21st.
