Ronnie Kray was a real London gangster, one of the Kray twins who dominated the city's East End in the 1960s, and he has since become a familiar figure in British crime drama. Tom Hardy played both Ronnie and his brother Reggie in Legend, the 2015 film that retold their story and gave the character a distinctive on-screen voice. Short lines from the film circulate online as reaction sounds because Hardy's controlled performance is instantly recognisable. This clip endures in edits where a calm warning carries more weight than shouting.
