Cruise's lawyers and the Church of Scientology are pondering suing Morton and the book's publisher, St. Martin's Press, for the staggering sum, the New York Daily News reported.
In the biography, Morton is said to claim without citing sources that Cruise's daughter Suri may have been conceived using the sperm of late Scientology founder L. Ron Hubbard.
"In her more reflective moments, (Cruise's third wife Katie Holmes) might have felt as if she were in the middle of a real-life version of the horror movie 'Rosemary's Baby,'" Morton reportedly wrote in the book Cruise's representative Paul Bloch called "a vicious and false attack on a man, his religion and his family."
"I find it disgusting and sick that this author would compare any child to 'Rosemary's Baby,'" Bloch told the News. "The author never interviewed anyone close to Tom Cruise. If they had, there would have been no book to be written."
