On February 26, 2007 a news conference was held at the New York Public Library by director James Cameron and Simcha Jacobovici to discuss their documentary "The Lost Tomb of Jesus", which discusses the 1980 finding of the Talpiot Tomb, which they claim is in fact Jesus' family tomb. In the film, they also suggest that the so-called James ossuary is actually the "missing link" from the tomb (at the original discovery of the Talpiot Tomb, there were ten ossuaries, however one has since been lost—Jacobovici suggests the James Ossuary could be the tenth from Talpiot). According to the film, "recent tests conducted at the CSI Suffolk Crime lab in New York demonstrate that the patina (a chemical film encrustation on the box) from the James ossuary matches the patina from the other ossuaries in the Talpiot tomb."
