Natalie Portman Would Love For Scarlett Johansson To Be Her Sister

Natalie Portman wishes she had a sister like Scarlett Johansson.

Natalie, who is an only child, loved having Scarlett as her on screen sibling in new royal drama 'The Other Boleyn Girl', in which they play Anne and Mary Boleyn.

Speaking at the film's royal premiere in London's Leicester Square last night, Natalie told BANG Showbiz: "I always grew up dreaming of having a sister. Working with Scarlett was wonderful, we became so close on set."

"I would cherish having a sister like Mary a lot more than my character Anne does, that's for sure. In the film Mary and Anne are battling for the affections of King Henry VIII and Anne is very scheming and cold. As someone who so longed to have a sister I wouldn't be like that at all."

Scarlett looked stunning on the red carpet in a Christian Lacroix one-shoulder silver dress, while Natalie dazzled in a claret Stella McCartney gown.

Eric Bana, who plays Henry VIII in the film, refused to be drawn on which actress he preferred kissing, saying coyly: "That's for me to know. I could never choose."

The screening was also attended by Britain's Prince Charles and his wife Camilla, the Duchess of Cornwall.

'The Other Boleyn Girl' sees a love triangle develop between Henry VIII and the Boleyn sisters, which takes a dark turn when Anne fails to provide him with a male heir.
