Depp will play the South Boston criminal mastermind, who was sentenced in November to two consecutive life terms plus five years after being found guilty on 31 counts of racketeering, money laundering, extortion and weapons charges (including his role in 19 murders).
The cast already includes Joel Edgerton as FBI agent John Connolly, and Benedict Cumberbatch is in talks to replace Guy Pearce as Whitey’s brother Bill. Also on the roll call are Fifty Shades of Grey actress Dakota Johnson, Juno Temple and Jesse Plemons.
Scott will play an FBI agent named Robert Fitzpatrick.
Crazy Heart helmer Scott Cooper is directing the movie, which is currently shooting in Boston.
This is the second star-studded movie that Scott is shooting this summer. After Black Mass, the actor heads to New York City for Sleeping With Other People, a romantic comedy that also stars Jason Sudeikis, Alison Brie and Amanda Peet.
Leslye Headland wrote and will direct the Sidney Kimmel Entertainment movie.
Scott recently starred and exec produced Overnight, a comedy with Jason Schwartzman and Taylor Schilling, alongside his wife Naomi Scott (through their Gettin’ Rad Productions) and Mark Duplass. He will also be seen this Christmas in Hot Tub Time Machine 2 and returns for season seven of NBC’s Parks and Recreation.
Scott is repped by WME.
