Gonna have to be someone who can certainly act the part of a ''well 'ard bastard''.
If it's a Brit based film, expect the likes of a rough looking Vinnie Jones or Jason Statham ( I know neither are the dog's danglies in reality before I get slated ), but they're your star candidates.

I've read Lenny McLeans biography, ( and the Krays ) and it's a small insight into a whole new world that the majority of people just don't know existed.
Guess I'd like to hear the story from a different side too.
Find the whole era very fascinating to be honest.
