HBO has optioned a Vanity Fair article about the wife of Johnny Carson’s longtime producer Freddie de Cordova — Beverly Hills socialite Janet de Cordova, reports Deadline.com.

HBO will develop the piece, "Once Upon a Time in Beverly Hills," into a movie about the relationship between Janet de Cordova and her housekeeper, Gracie Covarrubias.

"The de Cordova couple lived lavishly, and threw the most opulent A-list parties populated by the likes of Gary Cooper, Jack Benny, Frank Sinatra, Billy Wilder, Dean Martin, Jimmy Stewart, Lew Wasserman and Ray Stark. In the process, she spent way more than de Cordova earned," the article notes.

"By her side always was Covarrubias, her Mexican servant who tended to de Cordova’s every need, down to periodically stirring the drink de Cordova held in her hand," the story says.

After her husband died, Janet de Cordova had to sell her estate, and eventually moved to Mexico with her housekeeper, who had built a scaled-down replica of the de Cordova home, the story says.
