Blythe Danner's almost 70. You'd know her if you saw her. She has one of those mildly familiar faces that tend to pop up in movies and she's been acting in bits and pieces for decades. She's also Gwyneth Paltrow's mother. Chances are that if you watch TV in the United States you see her winning smile a couple of times a week.
"I have post-menopausal osteoporosis," grins Blythe, standing backstage in a theatre and looking thrilled with her diagnosis.
She's preparing for another night's performance; and heaven forbid anyone tells her to break a leg. But worry not for poor old Blythe. Relief comes in pharmaceutical form. The drug Prolia, Blythe tells us, has helped strengthen her bones and reduce her risk of fracture. "Break a leg," grins a middle-aged stage manager.
Blythe flicks him a flirty smile and heads for the bright lights. "Ask your doctor if Prolia is right for you," says her voiceover.
Drug advertisers in the US spend $5 billion a year in direct-to-consumer drug advertising. Media is awash with commercials - in the three and a half minutes between dances on Dancing With The Stars you can comfortably sort out your cholesterol and beat your depression and impotence - if you recommend to your doctor the brand you think is right for you. Experienced though the doctor is, Blythe Danner knows best.
