Lindsay Lohan is joining Keira Knightley in the "The Best Time of Our Lives," which John Maybury is in negotiations to direct for U.K.-based Sarah Radclyffe Prods.
Lensing is skedded to begin in April.
Script by Knightley's mother, playwright Sharman Macdonald, is based on the true story of the relationships among Welsh poet Dylan Thomas, his wife Caitlin (Lohan), his childhood friend Vera Phillips (Knightley) and her eventual husband, William Killick. It centers on the curious incident in which Phillips and Killick opened fire on the Thomas home with a machine gun and a hand grenade.
Rebekah Gilbertson, who is producing with Radclyffe, originated the project.
Gilbertson is the granddaughter of Phillips and Killick. Radclyffe co-founded Working Title with Tim Bevan in 1984 but left the company after Polygram took it over.
Lohan next stars in the Weinstein Co.'s "Bobby," to be distribbed by MGM, followed by Warner Bros.' "Georgia Rule."
Maybury directed Knightley in Warner Independent Pictures' "The Jacket."
