Lindsay Lohan has pulled out of a new Dylan Thomas biopic due to contractual issues, according to Life & Style magazine.

The actress was set to star in "The Best Time of Our Lives" with Keira Knightley, Matthew Rhys and Cillian Murphy.

Lohan was lined up to play poet Thomas' wife Caitlin MacNamara. Knightley will star as the poet's childhood friend, Vera Phillips.

Both women were involved with Thomas, to the chagrin of Vera's husband, William Killick.

Matthew Rhys will take the role of Thomas, with Irish actor Cillian Murphy as Killick.

The film scheduled to begin shooting early next month.
