Producer sues over Farrah Fawcett doc

Craig Nevius claims Ryan O'Neal threatened him

A producer is suing over Farrah Fawcett's upcoming documentary on her battle with cancer.

Craig Nevius filed the lawsuit in Santa Monica on Wednesday, seeking to regain creative control of the upcoming NBC special.

"Farrah's Story" is scheduled to air on Friday.

Nevius is suing Fawcett's longtime companion, Ryan O'Neal, as well as his business manager and Alana Stewart, who helped produce the documentary.

He claims the trio interfered with his rights to produce the documentary. Fawcett is suffering from complications from anal cancer that has spread to her liver.

He also claims O'Neal has threatened him.

A phone message left for Fawcett's publicist was not immediately returned Thursday.
