Kani, a South African, is best known for his apartheid-era, politically charged collaborations with playwright Athol Fugard. His new play — and his first as a solo playwright is Nothing But the Truth. It's a post-apartheid family drama inspired by the death of his brother, a poet who was killed by the South African police in 1985. Nothing But the Truth is currently playing at the Mitzi Newhouse Theatre at Lincoln Center in New York City. (This interview continues into the second half of the show).
