'Da Vinci Code' Author Dan Brown Takes Stand In Copyright-Infringement Lawsuit

Dan Brown is on the stand today to rebut accusations that he copied from other writers' work to produce his best-seller "The Da Vinci Code."

Authors Michael Baigent and Richard Leigh are suing "Da Vinci Code" publisher Random House for copyright infringement. They claiming Brown "appropriated the architecture" of their 1982 nonfiction book "The Holy Blood and the Holy Grail." Both books explore theories -- dismissed by theologians but embraced by millions of readers -- that Jesus married Mary Magdalene, the couple had a child and the bloodline survives.

Responding to questions from the plaintiffs' attorney, Brown said much of the research for the book was done by his wife, Blythe, who he called "deeply passionate about the sacred feminine."
