The remarkably versatile American-Australian actress Nicole Kidman celebrates her 50th birthday this week – now doesn’t that make us all feel old. Who would have predicted that as the wife of Tom Cruise playing mostly supporting roles she would step out of his shadow (and their marriage) so decisively and with such impact? She has done big genre pieces and smaller independent movies; tackled the erotic and the slutty, the withdrawn and widowed; the comic and the horrible; the mad and bad; the active and the intellectual. Her range, ambition and daring ensure her longevity just as her porcelain looks make her so memorable. Happy birthday to a constantly surprising screen presence.
