IF you google it, the scene is called 'Rear Window -- The Kiss'. Shot in technicolour, the camera pans around the view from the window and settles on a snoozing Jimmy Stewart, over whom an ominous shadow looms, growing closer.
He opens his eyes to find it's Grace Kelly, about to plant the perfect kiss on his lips. Not too long, not too short, incredibly pure, yet incredibly erotic. It's classic Hitchcock. All lighting and costumes and a beautiful icy blonde oozing unexpected sensuality out of a perfect pout.
And over this, yet another ominous shadow looms. Something truly insidious. The biopic.
Fast forward almost 60 years from that incredible moment in 'Rear Window' to another kiss.
But instead of it being all melty and tingly, it's Kidman, "pashing" husband Keith Urban in public. She looks on the verge of straining something vital as she forces her lower lip to touch her husband's. From any angle, it's about as sexy as something you'd find down the side of the couch.
It's inconceivable that someone as classy as Grace Kelly ever "pashed" anyone and while pictures of Kidman in full costume and make-up (pictured) capture the necessary style and look, can she really capture that incredible, ephemeral ' Essence of Kelly'?
Nicole Kidman is hugely successful and seems a genuinely lovely woman, but does she ever become anyone other than herself?
'Moulin Rouge'? Oh, it's Nicole Kidman, singing and catching consumption. 'The Hours'? Oh, it's Nicole Kidman with a massive fake nose. Bloody typecasting.
Kidman is a square peg in a Hollywood-shaped hole. But hark back to the flame-haired beauty and wild-eyed terror of 'Dead Calm' -- that was the girl who had Essence of Kidman.
If Kelly was the quintessential Ice Queen, then Kidman is Iceland.
And when it comes to channelling the princess, I have a funny feeling Kidman might be able to walk the walk, talk the talk and look the look, but can she amount to more than just a pretender to the throne?
