except that Tom Hardy, who played both Reggie and Ronnie with equal despicability, showed his acting talents. The fact that Ronnie Kray wore glasses was a minor distinction. The difference in their facial expressions, speech patterns, vocabulary and delivery was convincing enough for me, had I not known, to believe that two separate actors played the parts. So, Tom Hardy deserves an award for his acting. 
The movie narrated by Frances Shea (Emily Browning) the young wife of Reggie, after she committed suicide, begins with a horrific scene of a man being tortured by the Torture Gang, rival of The Firm, the gang led by the Kray twins who terrorized London during the 1950s and 1960s with robberies, murders, racketeering, and worse.
