Miller takes part in World War II drama 'Flare Path' as a former actress married to a fighter pilot.
Sienna Miller is joining her boyfriend Jude Law in London's West End this year - she has signed up to star in a new production of Terrence Rattigan's "Flare Path".
Law recently announced he will be returning to the London stage in 2011 to star in Eugene O'Neill's play "Anna Christie", and now his former fiancee has also signed up to lead the cast of a theater production in the U.K. capital. Miller will play a former actress married to a fighter pilot in the World War II drama, which will be directed by revered theatre mogul Sir Trevor Nunn.
She says, "Once we're in the rehearsal room there's no one like Trevor to tell a story like this, and to uncover the subtext." The play will open in March.
