Sienna Has The Best Time After Lindsay's Exit

The Mean Girl is out and the Factory Girl is in.

Sienna Miller has replaced Lindsay Lohan in the upcoming film The Best Time of Our Lives, after Lohan pulled out of the project last week, reportedly due to issues with her contract.

The film centers on Welsh poet Dylan Thomas (Matthew Rhys) and his wife, Caitlin MacNamara (Miller), and the events that led up to a bizarre 1945 incident in which Thomas' childhood friend Vera Phillips (Keira Knightley) and her eventual husband, William Killick (Cillian Murphy), opened fire on the Thomas home with a machine gun and a hand grenade.

Knightley's mother, Sharman Macdonald, penned the screenplay for the film, which is slated to begin shooting next month in Wales.

Last October, Lohan stirred up some serious buzz around the project when she hinted at the possibility of steamy scenes between herself and Knightley.

"Keira is older than me, but she kind of has a mysterious relationship with my lover and there's somewhat of a lesbian undertone," Lohan told MTV News.

Now it seems any onscreen girl-on-girl action will go down between Miller and Knightley instead.

It's the second film Lohan has opted out of in recent months. In February, she dropped out of the big-screen adaptation of Oscar Wilde's A Woman of No Importance in order to focus on her recovery after her stint in rehab. Jessica Biel stepped in to take over the role, starring opposite Annette Bening.

Though few actresses can match Lohan when it comes to generating tabloid fodder, Miller has certainly had her headline moments.

Aside from suffering through the public humiliation of ex-fiancé Jude Law's acknowledgement of his affair with his children's nanny, Miller was also widely criticized last fall for bashing the city of Pittsburgh in an interview with Rolling Stone. (She later apologized.)

On the other hand, she has yet to be hospitalized for exhaustion, check into rehab, get into numerous paparazzi-related fender benders or be publicly chastised by the producer of one of her films for bad behavior.

Which is to say, she has a comparatively spotless track record.

Up ahead, Lohan stars in Georgia Rule, opening next month, and I Know Who Killed Me, opening July 27, while Miller appears in Interview, opening July 13, and Stardust, opening Aug. 10.
