Although " A House of Dynamite" star Idris Elba did say at the Netflix release's Venice Film Festival press conference that he "does not have the courage to be in politics," he certainly does not shy away from playing heads of state on film. Over a decade after his Golden Globe-nominated performance as Nelson Mandela, former President of South Africa, in "Long Walk to Freedom," the British actor has played both the British Prime Minister in " Heads of State," and the President of the United States in the new political thriller from Best Director Oscar-winner Kathryn Bigelow.
