Black Mass: Why you won't be seeing Sienna Miller in the Johnny Depp gangster movie after all

Cinema-goers expecting to watch Sienna Miller in upcoming gangster biopic Black Mass will be disappointed, after the actress was cut from the movie at the last minute.

Miller had filmed her scenes as Catherine Greig, girlfriend of infamous Boston criminal Whitey Bulger, last summer but audiences will not be seeing them.

Director Scott Cooper has explained that although Greig's performance was "fantastic" the decision to edit her out of the final film "came down to narrative choices". He opted to tighten the focus on Bulger's earlier years before leaving Boston because his fugitive years, involving Greig, were "less dramatic".


Miller said last November that she had been working with a dialect tutor to improve her Boston accent for the role.

"Up until the day before I flew here, I couldn't do it and it sounded stupid," she told the Boston Globe. "I was sort of religiously watching ever film ever set in South Boston: Good Will Hunting, Gone Baby Gone, The Town. Catherine had a thick accent, so I hope I do it justice. The story's in the right hands and it was amazingly fun to come in."

Black Mass premieres worldwide at the Venice Film Festival today and reaches UK cinemas on 27 November. Benedict Cumberbatch, Joel Edgerton, Juno Temple, Dakota Johnson, Corey Stoll and Kevin Bacon also star.
