Another film about a famous hoaxer is in the works. Julian Temple plans to make a movie about the art forger Elmyr de Hory. From reuters:
The British filmmaker will take on the story of art faker Elmyr de Hory, who created and sold forgeries of paintings by the likes of Picasso and Matisse to collectors around the world between the 1940s and 1960s.
De Hory, a Hungarian native, told his story to the equally notorious hoax biographer Clifford Irving (played by Richard Gere in "The Hoax" in 2007) for the book "Fake!" Additionally, Orson Welles made a documentary about him, "F For Fake."
