Sienna Miller, and not Lindsay Lohan, will star with Keira Knightley, Cillian Murphy and Matthew Rhys in The Best Time of Our Lives, the John Maybury-directed drama which begins shooting in early May in Wales.
Written by Knightley's playwright mother Sharman Macdonald, the film is based on a rivalry between two women over the Welsh poet Dylan Thomas (Rhys). Miller will play his wife, Caitlin MacNamara, and Knightley plays his childhood friend Vera Phillips.
According to Variety, Lohan had long been expected to play the role of Caitlin, but she and the financiers couldn't come to a deal and she dropped out.
Rebekah Gilbertson is producing with Sarah Radclyffe. Capitol Films is financing.
