Sienna Miller is replacing Lindsay Lohan in a steamy film, which has lesbian scenes between Keira Knightley and Sienna.
Miller is replacing Lindsay as Caitlin - the wife of Welsh poet Dylan Thomas - in the flick - The Best Time Of Our Lives, scripted by Keira’s mother Sharman Macdonald.
Lindsay withdrew the film role because she was not able to reach a deal with the financers.
Keira will be playing the character of Vera, a childhood friend of Dylan, the poet and Vera is said to have a sexual relationship with him and his wife. Matthew Rhys is playing the role of the hard-drinking poet.
Speculation of Lindsay dropping out from the movie started the last week, when she did not come for the scheduled shoot. LiLo and Keira Knightley are at loggerheads since then.
Shooting with Sienna will start in Wales early next month.
