In the London of the swinging sixties, identical twins rise from the East End to rule the city's underworld, one all velvet charm and business ambition, the other a paranoid, violently unhinged force of nature. As their nightclubs draw celebrities and their rackets draw police attention, the fragile bond between the brothers begins to fray toward ruin. Brian Helgeland stages the gangster saga through a bravura dual performance from Tom Hardy, who plays both siblings with unnerving distinction. Stylish and darkly funny, it glamorizes and then dismantles the myth of the brothers who briefly owned London.
