Dakota was snapped on set filming Black Mass��in Boston, Massachusetts.�The 24 year old is cast as Lyndsey Cyr, the ex-girlfriend of Whitey Bulger (played by Johnny Depp).

Johnny Depp turned�51 yesterday.�In the film, Johnny stars as�real-life mobster James “Whitey” Bulger, who received two life sentences plus five years for murder. Depp’s transformation for the role is quite extreme. His striking good looks are covered up with full makeup, colored contact lenses and a bald cap with thinning blonde hair!

Benedict Cumberbatch and Sienna Miller also star in Black Mass.
