Olivia Wilde, Daniel Craig And Harrison Ford At The UK Premiere Of Cowboys And Aliens

Olivia Wilde's been busy on the campaign trail for what is tipped to be the blockbuster of the summer, Cowboys and Aliens, and the whole gang hit London for the UK premiere.

On first glance, the dress appeared dramatic, but conservative - until Olivia turned to the side to reveal completely sheer panelling.
