Mbongeni Ngema, writer of the acclaimed musical Sarafina about student riots in apartheid Soweto, was killed in a car crash on Wednesday at the age of 68, his family announced. Ngema died just as the 1992 movie, developed with legendary jazz musician Hugh Masekela, was making a return with a screening at this year’s Cannes film festival classic section and a streaming release.
