Sienna Miller Has Had Nightmares About Starring in 'Cabaret'

Sienna Miller is presented with a giant bouquet of flowers during her curtain call for her opening night performance in Cabaret on Tuesday (February 17) at Studio 54 in New York City.

The 33-year-old actress took over the role from Emma Stone and will play the part of Sally Bowles for the next six weeks.

Sienna appeared on Good Morning America the day before and talked about the nightmares she has had about not being sexy enough for the show.

“It’s a really saucy part and there are gorgeous costumes and in one of the scenes I do this dance… in this sexy black cap, but I had this dream that I did the first show and my boyfriend [Tom Sturridge] came backstage and said it was really underwhelming,” Sienna said. “He was like, ‘You’ve got to pick it up.’ [Co-star] Alan Cumming wouldn’t look me in the eye… and I woke up in [a panic].”
