The March, a Robert Redford-produced documentary on the historic March on Washington, will air on PBS in August to mark the event’s 50th anniversary.

The March on Washington culminated in Dr. Martin Luther King Jr.’s iconic “I Have A Dream Speech.” Rarely seen footage from that day on Aug. 28, 1963 will be prominently featured in the documentary, notes The Hollywood Reporter.

John Akomfrah directed the film, which Redford’s Sundance Productions co-produced with U.K. studio Smoking Dogs Films. It will focus on the “I Have A Dream” speech and the events that lead up to the March on Washington with interviews from those who were there and helped organize it. Over 250,000 people gathered on the National Mall to see King give his stirring speech.

“The story of people who suffered profound injustice in America and fought it with sacrifice and courage is something we should never forget,” Redford said in a press release. “I hope the generations who see this film will be inspired by it.”

“The March is the watershed moment of the Civil Rights Movement, the culmination of a hundred years of activism against segregation and social injustice for people of color in the U.S.,” Akomfrah commented. “Retelling this story is my small contribution to that monumental struggle.”

PBS is producing a wave of content for the March’s anniversary. NewsHour will have special coverage and The March @ 50 will be featured on the PBS Black Culture Connection.

The March airs on PBS on Aug. 27.

In other Redford news, the Oscar winner was spotted on the set of Captain America: The Winter Soldier in Cleveland, Yahoo! News reported last week. It is the legendary actor’s first comic book movie.
