Actress says it reveals every nook and cranny

Sienna Miller‘s action figure is completely in proportion.

The actress character, The Baroness, from new movie GI Joe: The Rise Of Cobra has been turned into a toy figure by Hasbro.

I got measured in this pod so the doll is exactly to scale, every nook and cranny, says Sienna, 27.

Kids will be killing me, because I am the baddie.

But Sienna, who recently split from Balthazar Getty, reckons her relatives will love the toy.

Ill have happy nieces and nephews at Christmas time, she tells the Daily Star.
