CNET:

At the heart of the film, acclaimed British actor Hardy plays twin brothers Reggie and Ronnie Kray, notorious real-life gangsters who ruled the London underworld in the 1960s by killing and robbing, while also rubbing shoulders with celebrities in the nightclubs they owned. Although the film’s story could be more focused, Hardy is captivating — and justly award-winning — in the twin roles.

“I read the script as if it was going to be two actors playing Reggie and Ronnie,” said Pope. “It came as a huge surprise to me that they had signed Tom Hardy up to play both roles! From being a fairly straightforward narrative, it turned into an extremely technically challenging production.”

I’ve seen this film and the performance by Hardy is made all the more incredible by the visual effects.
