Keira Knightley to Star in The Best Time of Our Lives

The full-length feature is based on a true story, and was written by the mother of the 21 year-old actress.  The project has been in the works for four years.

The Best Time of Our Lives tells the complex relationship of poet Dylan Thomas, his wife, Caitlin, friend Vera Phillips (Knightley), and her future husband, Willliam Killick.

John Maybury will direct Knightley again in the project, as he did for the film The Jacket.

Filming for The Best Time of Our Lives is set to begin in April.
