|Psychopath who preys on cops|Blitz(2011)

You meet Barry at the funeral of Detective Roberts. He looks just like a normal policeman, although a little nervous, but mostly he's not in trouble unless you know he's a maniac called Blitz.

Hell yeah, Aidan Gillen! Only recently started getting familiar with his film roles. Petyr is harder to do, so let Barry be the first. Also planned are Janson from The Maze Runner, Aberama Gold from Peaky Blinders and Nelson Rathbone from Shanghai Knights.
