PHOTOS: Sienna Smiles through So-So Reviews of 'After Miss Julie'

Sienna Oct. 23"

Sienna Miller celebrated her Broadway debut in After Miss Julie last night at the American Airlines Theatre and then partied afterward with her co-stars at Espace. While Sienna was all smiles about her performance, others were not. The NY Times said, "Ms. Miller registers as a healthy, sane young woman with good diction, good posture and great legs. Commendable as these attributes are, they are of limited use in portraying a tautly wound, death-courting neurotic who is eaten alive by her own demons."
