2pm: Movies

The UCLA Film and Television Archive’s Kids’ Flicks series continues with two family classics. Elizabeth Taylor (in perhaps her most perfect performance) plays a passionate little girl who loves horses and wants to win the Grand National in the 1945 charmer “National Velvet.” The film co-stars Mickey Rooney, Donald Crisp, Anne Revere and Angela Lansbury. The 1979 “The Black Stallion,” a rapturously beautiful film about a young boy and a gorgeous wild horse, also features Rooney, who plays an aging trainer. Both films are rated G.

all day / Museum

It is only appropriate that the exhibit “I Am My Brother’s Keeper: The Life and Times of Simon Wiesenthal” opens on Yom Hashoah, or Holocaust Remembrance Day, at the Museum of Tolerance. Born in what is now Ukraine, Wiesenthal, who is 90 and lives in Vienna, was an architectural engineer until 1939 when the German-Russian nonaggression pact began the Red purge of Jews. Wiesenthal survived incarceration, labor and concentration camps, and after the war became a famed “Nazi hunter,” investigating 6,000 cases that led to more than 1,100 convictions of war criminals. “I Am My Brother’s Keeper” contains 200 photos, documents and Wiesenthal’s sketches made just after his liberation from Mauthausen in 1945.

* “I Am My Brother’s Keeper: The Life and Times of Simon Wiesenthal,” the Museum of Tolerance, 9760 W. Pico Blvd., Los Angeles. Ends Aug. 29. Open Monday-Thursday, 10 a.m.-4 p.m.; Friday, 10 a.m.-3 p.m.; Sunday, 11 a.m.-5 p.m. $8.50; $6.50 seniors; $5.50 students; $3.50 ages 3-10. (310) 553-8403.
