Tell them about the honey, luvvy: The precocious Kate had acting in the blood and, having studied drama since the age of 11, made her small-screen debut at 13 with the Honey Monster in a Sugar Puffs commercial.
Titanic: The adolescent Kate put on a few pubescent pounds. At 15 she weighed 13 stone. Though she managed to lose the weight, during the filming of Sense and Sensibility Emma Thompson noticed that she was skipping meals: "Do you want to be a twig," she demanded, "or a heart and soul that is true?"
Heavenly beginnings: Kate trod the boards for a few years, popped up in the early Nineties drama Anglo-Saxon Attitudes, and served time on Casualty before Peter Jackson gave her her big break as Juliet Hulme, the homicidal teen fatale, in Heavenly Creatures.
Beautiful one: In 1996, Kate was selected by the American magazine People as one of the world's 50 most beautiful people.
Ship wretch: Poor Kate wasn't able to watch herself go down with Leonardo at the premiere of Titanic last year because she was laid low with food poisoning in Morocco while working on her next project, a film adaptation of Esther Freud's novel Hideous Kinky.
Drowning not waving: Kate was forced to publish an open letter of apology following an interview in which she claimed that James Cameron had nearly drowned her during the filming of Titanic.
The forecast: Rumours that the 22-year-old is to play Luke Skywalker's mother in George Lucas's Star Wars prequels appear to be unfounded, but it seems she is likely to star with Glen Close in a film of Brian Friel's play Dancing at Lughnasa and is thought to be appearing in a remake of The 39 Steps with Liam Neeson and Ralph Fiennes.
