The 36-year-old British star of The Mummy and About A Boy is seen in Snow White's famous hairband and dress in a portrait shot by celebrity photographer Annie Leibovitz.

The images for Disney's Year of a Million Dreams celebration, which has been extended to the end of next year, also see Dame Julie Andrews posing as the Blue Fairy from Pinocchio and men's world tennis number one Roger Federer as King Arthur.

They come after David Beckham portrayed the dragon-slaying horse-riding Prince Phillip for Disney earlier this year, along with Beyonce Knowles as Alice In Wonderland and Scarlett Johansson as Cinderella.

Weisz, who is seen with a blue and white bird resting on her hand while she befriends animals in a forest, said: "I'm a woman now, but it doesn't matter what age your are, I think you always want to be Snow White.

"It is every little girl's dream. And to be photographed by Annie, one of the great living artists, is really an amazing collaboration."

Ms Leibovitz said: "She was so Snow White. Rachel Weisz was just a perfect Snow White. When you work with this calibre of actor, it takes just a few seconds, a few minutes, to do these pictures."

Dame Julie, who has a long-standing relationship with Disney and played Mary Poppins in 1964, said of her photograph: "It's a symbolic photograph of all the wonderful Disney images."

Federer, 26, is also seen with his sword drawn posing on a rock as the gallant King Arthur in an image set against a background shot at Tintagel Castle in Cornwall.

Federer, who is pictured with his red cape flowing beside a rolling sea, said: "I did feel strong on that rock. I'm higher than everybody. I got the sword. I got the armour. It felt very funny and good actually."
