The linked article about Joan Collins from 2005 briefly, if clumsily, explains the concept:
[quote] This is a show business expression referring to ageing screen beauties who have become recluses, in the way of Norma Desmond, the fictional heroine of Sunset Boulevard.
RETIRED screen siren Elizabeth Taylor was the violet-eyed, raven-haired temptress who created the template for the modern movie goddess as celebrity, putting ever more appearances in the gossip columns than at the film studios.
But at 72-years-old she is said to have ``shut the door'.
This is a show business expression referring to ageing screen beauties who have become recluses, in the way of Norma Desmond, the fictional heroine of Sunset Boulevard.
In director Billy Wilder's original film script, Norma dismisses her long absence from the screen with the memorable words: ``I'm still big, it's the pictures that got small. '
It happens eventually to even the greatest glamour girls, including the enigmatic Greta Garbo.
Or they end up devoted only to animals, as in the case of Brigitte Bardot, Tippi Hedren and Kim Novak.
One particularly sad case was the lovely Rita Hayworth, whose life sank into sozzled senility.
The only one nearly to escape was Marlene Dietrich, who reinvented herself as an international cabaret artiste (deferring reclusiveness to her 90s).
In contrast to Dame Elizabeth, who claims to be British (being born in Hampstead), is our own better, truer Brit, Joan Collins.
In spite of being (at 71) only a year younger than La Taylor, Joan is desperate to be back in front of the cameras with a part in the new US hit comedy series Desperate Housewives.
She has been badgering her agent to suggest her to the programme's producers as 40-something Teri Hatcher's desperate mother.
Age has not withered her ambition.
How we ever lost the empire with memsahib pensioners of this calibre of spunkiness is one of life's continuing mysteries.
