Sienna Miller @ 'Interview' Premiere

Sienna Miller grabs lunch at Times Square’s Blue Fin restaurant with co-star Steve Bushcemi and then heads to the NYC screening of Interview at the Tribeca Grand Screening Room on Wednesday. (Sienna wore a Chanel dress with a lace bodice and slit skirt.)

During interviews the last few days, Sienna shared that Interview took just nine days to shoot (there are only two characters in the entire movie).

The British actress also admitted to being a bit clumsy, even on set. In fact, two moments in the movie are improvisational but it made the final cut of the film! The first is Sienna‘s character sipping wine and then spilling it all over herself. The second is when she Buscemi are feverishly making out and her head hits the kitchen counter.

Interview hits theaters in limited release on Friday, July 13. More pix inside…
