Here‘s the Web site of one of my favorite actors. Ricky Jay is a real-life master of deception who makes a living as a character actor. You probably recognize him from a David Mamet or P.T. Anderson film.
I heard an interview with him on NPR about 5 years ago. He’s a little sheepish about it, but I think he was a real con man back in the day. (He always plays one in Mamet’s films.) Now, he sells this knowledge through his company, “Deceptive Practices.”
The firm’s slogan: “Arcane knowledge on a need-to-know basis.”
UPDATE: Here’s the link to the NPR interview.
