Carmen Ejogo, who plays Coretta Scott King in Boycott, went on to reprise the role thirteen years later in Selma (2014).
Carmen Ejogo and Jeffrey Wright, who play married couple Coretta Scott King and Rev. Dr. Martin Luther King Jr. in this film, met on the set of Boycott and were married in 2000. They had two children and divorced in 2014.
Jeffrey Wright, who played Rev. Dr. Martin Luther King Jr. in this movie, would go on to play Adam Clayton Powell Jr. in Bayard Rustin (2023) which details the planning of the March on Washington, where King gave his famous "I Have a Dream" speech. In that movie, Bayard Rustin was played by Colman Domingo, who played Ralph Abernathy in Selma, another movie about King and the Civil Rights Movement.
This would be Whitman Mayo's final TV appearance before his death three months later.
