Today's top ten list was inspired by the passing of the great Joan Fontaine, half of Hollywood's most embittered AND most successful sibling rivalry, all-female division. Usually when a movie star has a sibling, one is considerably less successful than the other which is why the Fontaine & de Havilland business was so enduringly fascinating. (If we're talking mixed gender siblings only Warren Beatty & Shirley Maclaine are truly comparable in terms of parallel mega-careers). I'm dedicating this list to the Talmadge sisters, silent screen stars (though most of their work did not survive) as well as the one and only Catherine Deneuve and Françoise Dorleac (her gorgeous elder sister who died way too young)... those Young Girls of Rochefort. But Rochefort is a long way from Hollywood.
HOLLYWOOD'S TOP TEN FOURTEEN (ACTRESS) SISTER ACTS
14 Kate Mara (1983-) & Rooney Mara (1985-)
Rooney, currently playing Joaquin's ex-wife in Her, became a very big deal two years ago with The Girl With the Dragon Tattoo and Kate is currently working the Netflix original House of Cards. If Hollywood futures are kind they'll climb this informal list.
