Sienna Miller brought the sexy to a NYC screening of her latest flick, The Mysteries of Pittsburgh (you know, the one where she dissed the city during filming?) - but I must admit, it's a little too much red!

This is a VERY attractive woman, but another color might've worked better...

Co-star Maggie Gyllenhaal was also present for the showing, as well as Anna Wintour. Random, right?
