The original film about the subject "The Krays" (1990) had Billie Whitelaw as their mother and, somehow, she dominated my memory of the film. Here the twins have a mother but she is, on the film, a distant character and that's what I missed here. I missed their interaction. She clearly had a massive influence in their characters but in Legend, those pieces of the puzzle are unfortunately missing. But, Tom Hardy compensates for any flaws. He is extraordinary, twice. The twins are total individuals, totally two people. What they carry in common is a sort of sexual danger, one explicitly the other implicitly but both as powerful. They dare us to get close. Amazing performance(s)
