Sienna Miller Has 'Great Chemistry' with 'Flare Path' Cast

Sienna Miller wears Twenty8Twelve as she makes a stylish exit from Theatre Royal Haymarket after performing in Flare Path on Monday (March 14) in London, England.

Earlier in the day, the 29-year-old actress and her older sis Savannah launched their latest Twenty8Twelve collection at Selfridges.

Flare Path casting director Maggie Lunn recently shared that she approached Sienna for the play after seeing her on Broadway last year in After Miss Julie.

“Sienna has a great working relationship with the rest of the cast. There is great chemistry on stage,” Maggie told the U.K.’s Independent.
