Almost 50 years since the assassination of US President John F Kennedy in Texas, a new film is exploring the shooting through the eyes of ordinary people.
Parkland examines the events of November 22 1963 from the perspective of the medical staff who treated the president, the detectives who sought his killer, and the man who filmed that dramatic moment in history.
