KERA will host a special screening of the film “Freedom Summer” at 6:30 p.m. Tuesday at the station, 3000 Harry Hines Blvd., Dallas. Register by 5:30 p.m. here. The documentary focuses on the effort to get blacks registered to vote in Mississippi. Join KERA and our community partners – Dallas Faces Race, The Embrey Family Foundation, the Embrey Human Rights Program at SMU and the South Dallas Cultural Center – forvideo clips from the documentary and a panel discussion. The film airs June 24 on KERA-TV (Channel 13). KERA’s ongoing radio series, “The Voices of Freedom Summer,” features Rev. Peter Johnson, who was a 19-year-old civil rights worker in 1964. On Monday, historian Bruce Watson, whose book serves as the source material for the documentary, appeared on KERA’s “Think.” Listen to that conversation here.
