The Georgia congressman was one of the Big Six civil rights leaders, who included Martin Luther King Jr, and helped organise the 1963 March on Washington.
He was best known for leading some 600 protesters in the Bloody Sunday march across the Edmund Pettus Bridge in Selma.
He announced in December that he had been diagnosed with advanced pancreatic cancer.
DuVernay, who directed the film Selma about the 1965 march, wrote on Twitter: “Thank you for your care and kindness, your advice and understanding.
“Will never forget what you taught me and what you challenged me to be. Better. Stronger. Bolder. Braver. God bless you, Ancestor John Robert Lewis of Troy, Alabama. Run into His arms.”
