For Pierce Brosnan, Conrad Harrigan, head of London’s scariest, toughest and most brutal clan, ranks among the darkest characters he’s ever played.

Tom Hardy has collected a number of intimidating roles, from the brutish title character in 2008's "Bronson" about the British criminal, to his dual performance as the Kray twins in 2015's "Legend," to his role as the Jewish gangster Alfie Solomons in " Peaky Blinders ."

From legendary crime film director Guy Ritchie, this new show stars Tom Hardy as Harry Da Souza, a fixer for the London-based Harrigan crime family. That family is led by patriarch Conrad Harrigan (Pierce Brosnan), while his wife, Maeve (Helen Mirren) and son Kevin (Paddy Considine) are also key cogs in the Harrigan crime machine.
