Sienna Miller is the latest actress lined up to share Keira Knightley's bed in her raunchy new film.
Keira, 22, was supposed to be starring alongside Lindsay Lohan in a movie about Welsh poet Dylan Thomas and his romance with two women. But unfortunately Lindsay had to pull out over problems with her contract.
Now Sienna, 25, had stepped in to fill the void.
'Everyone was gutted when Lohan quit,' a source tells The Sun. 'We knew love scenes between her and Keira would pull in the punters.
'But when Sienna said she wanted the role, our fears were laid to rest. The sex scenes will go down in movie history.'
