Deadline: Playing out of competition, today’s Venice Film Festival gala entry Black Mass screened for press at an early call this morning with strong applause at the end — twice. Audiences should be cautioned to stick around as there’s a key footnote at the end of the Scott Cooper-helmed crime drama. Johnny Depp has been getting some career best notices for his chameleon-like turn as James “Whitey” Bulger, the notorious leader of Boston’s Winter Hill mob who is now serving two life sentences for murder and other crimes. Bulger was a ruthless mob kingpin in 1970s Boston who spent a decade on the FBI’s Ten Most Wanted list. He went on the lam in 1994 and was finally captured in 2011 in Santa Monica. He turned 86 yesterday.
