"Beyond Vietnam: A Time to Break Silence", also referred as Riverside Church speech, is an anti-Vietnam war and pro-social justice speech delivered by Martin Luther King Jr. on April 4, 1967, exactly one year before he was assassinated.
 The major speech at Riverside Church in New York City, followed several interviews and several other public speeches in which King came out against the Vietnam War and the policies that created it.
 Some, like civil rights leader Ralph Bunche, the NAACP, and the editorial page writers of the "Washington Post" and the "New York Times" called the Riverside Church speech a mistake on King's part.
 Others—including James Bevel, King's partner and strategist in the Civil Rights Movement—called it King's most important speech.
 It was written by activist and historian Vincent Harding.
The April (titled Martin Luther King and the March on Washington in the United Kingdom) is a BAFTA-nominated documentary directed by John Akomfrah and narrated by Denzel Washington.
 It is about the historic 1963 March on Washington for Jobs and Freedom - largely remembered for Martin Luther King's famous and iconic "I Have a Dream" speech delivered on the steps of the Lincoln Memorial in Washington, D.C. It formed the centrepiece of a special week of programs and online events and activities celebrating the 50th anniversary of the March.
"I Have a Dream" is a public speech delivered by American civil rights activist Martin Luther King Jr. during the March on Washington for Jobs and Freedom on August 28, 1963, in which he calls for an end to racism in the United States and called for civil and economic rights.
 Delivered to over 250,000 civil rights supporters from the steps of the Lincoln Memorial in Washington, D.C., the speech was a defining moment of the Civil Rights Movement.
Ernest Samuel McBride, Sr (November 20, 1909 – May 5, 2007) was an African American civil rights activist and community leader based in Long Beach, California.
 He fought to improve the working prospects and conditions of African Americans in the shipyards, grocery stores, housing, police and fire departments in Long Beach.
 He was a co-founder of the Long Beach chapter of National Association for the Advancement of Colored People (NAACP).
 Like Martin Luther King, Jr., McBride employed Mahatma Gandhi's model of peaceful protest to achieve civil rights gains.
 He became a target of the FBI's CONINTELPRO, which targeted many of the country's civil rights organizations and leaders, including Martin Luther King, Jr. - most famously resulting in the FBI - King Suicide Letter.
 McBride's legacy is memorialized in numerous awards, historic land marking of his home, and the naming of a high school and park.
The March on Washington for Jobs and Freedom, the March on Washington, or The Great March on Washington, was held in Washington, D.C. on Wednesday, August 28, 1963.
 The purpose of the march was to advocate for civil and economic rights for African Americans.
 At the march, Martin Luther King Jr., standing in front of the Lincoln Memorial, delivered his historic "I Have a Dream" speech in which he called for an end to racism.

King Kennedy is an upcoming drama thriller film set in the 1960s made entirely from archive material.
 The film stars some of the most prominent characters from 1960s America, including US President John F. Kennedy, Robert F. Kennedy, the civil rights movement leader Martin Luther King, convicted assassins Lee Harvey Oswald and Sirhan Sirhan and the film world's brightest icons of that time Marilyn Monroe and Frank Sinatra.
 The plot line revolves around the concepts of truth and freedom, but pursues further towards deception, intrigue, conspiracy and murder, and features some of the most memorable moments in 1960s America, including Marilyn Monroe's world-famous "Happy Birthday, Mr. President" at Madison Square Garden and Martin Luther King's "I Have A Dream" speech on the steps of the Lincoln Memorial in which he called for racial equality and an end to discrimination.
 The film is designed primarily to remind, focusing on the characters and events that build up to the assassinations of John F. Kennedy, Robert F. Kennedy and Martin Luther King as their apparent determination to shy away from war, discrimination and hatred became ever more publicized.
The Martin Luther King Jr.
 Outpatient Center (MLK OC), formerly known as Martin Luther King Jr.
 Multi-Service Ambulatory Care Center (MLK-MACC), Martin Luther King Jr./Drew Medical Center (King/Drew) and later Martin Luther King Jr.–Harbor Hospital (MLK-Harbor or King–Harbor), is a public urgent care center and outpatient clinic in Willowbrook, an unincorporated section of Los Angeles County, California, north of the city of Compton and south of the Watts neighborhood of Los Angeles.
 Founded as a major public hospital, it was shut down in August 2007 because of its poor record of patient care.
 The urgent care center and outpatient clinic, however, remain operating on the site.
 There are plans to reopen the facility in 2013 as a smaller hospital under a partnership between Los Angeles County and the University of California as a nonprofit organization governed by a seven-member board of directors.
