Ricky Jay is a world-renowned magician, author, historian and actor (often a mischievous presence in the films of David Mamet and Paul Thomas Anderson) -- and a performer who regularly provokes astonishment from even the most jaded audiences. Deceptive Practice traces Jays achievements and influences, from his apprenticeship at age 4 with his grandfather, to such now-forgotten legends as Al Flosso, Slydini, Cardini and his primary mentors, Dai Vernon and Charlie Miller. Featuring rare footage from his 1970s TV appearances (doing 3-card Monte with Steve Martin on The Dinah Shore Show) and told in Jays inimitable voice, this is a remarkable journey inside the secretive world of magic and the small circle of eccentrics who are its perpetual devotees.
