Is Yvonne DeCarlo, the reclusive actress who played Lily on the 1960s sitcom The Munsters, preparing for a comeback? At least her son seems to think so.

It's been a tough couple of years for the 77-year-old star, who lost a son, Michael, in 1997, and then suffered a stroke a year later. Today, she lives outside of the limelight beside a golf course near remote Solvang, CA.

"She keeps up her correspondence and I think plans her reentry into the business," says son Bruce Morgan on tonight's A&E Biography (8 pm/ET). "I want to see her do that because she's an old trouper. She's not gonna be happy sitting up on a golf course for a long time.

"My mother can be very emotional and other times she can be a brassy warrior," says Morgan of his mom, who rose to fame playing opposite Charlton Heston in 1956's The Ten Commandments.

The Biography episode also covers DeCarlo's initial reluctance to take on the role of TV's ghoulish Lily Munster following her successful career in movies. Says biographer James Parish: "At first she was embarrassed by the thought of doing it, but her agents and her bankbook told her, 'Audition for this; you need the part and you need the money... it might lead to something.' "
