Weekend TV : Apartheid Problems Take KCET Spotlight; Peter Ustinov Reports on His China Trip

An afternoon of apartheid, an evening in China and a dark night hunting Nazis round out this weekend’s small-screen schedule.

KCET Channel 28 devotes five hours to programs about apartheid and South Africa beginning at 1 p.m. today. “Sanctions and Apartheid: A Firing Line Special From South Africa” kicks things off, with William F. Buckley interviewing five South African leaders, including foreign minister Pik Botha, progressive member of Parliament Helen Suzman and Zulu Chief Mangosuthu Buthelezi.

The rest of the afternoon features cultural performances by South African artists and a documentary about Winnie Mandela.

At 9 tonight, Peter Ustinov spends an hour in China. “Beijing to Tibet,” the first of two programs chronicling Ustinov’s journey through the world’s most populous nation, focuses on the mixing of old and new cultures.

Sunday, Ben Kingsley stars as Simon Wiesenthal in the HBO movie “Murderers Among Us,” beginning at 8 p.m. The three-hour movie tells the story of the man who, after being liberated from a Nazi death camp in 1945, committed his life to tracking down the men responsible for the Holocaust.
