BEVERLY HILLS, CALIFORNIA, UNITED STATES  (REUTERS) - Oprah Winfrey is donating 12 million dollars (USD) towards a new museum in Washington DC dedicated to African American history. After previously giving $1m to the National Museum of African American History and Culture, her total contribution is its biggest so far. The museum on Washington's National Mall, which is due to be completed in 2015, will house a 35-seat theater named after Winfrey.

A rare 75-year-old comic book featuring the debut of Superman found in aMinnesota home's wall fetched $175,000 at auction. The comic book, Action Comics No. 1 from June 1938 had been estimated to sell for about $100,000 and is one of only about 100 remaining copies of the 250,000 originals. The book's condition was graded 1.5 out of 10 because its back cover was accidentally ripped shortly after it was found. A mint condition copy of the same comic would command about $3 million (USD).

The first teaser trailer for "Diana" has been released, showing Naomi Watts in the title role. Directed by Olivier Hirschbiegel, the film focuses on the last two years of Diana's life, including her campaign against land mines and her relationship with heart surgeon Dr. Hasnat Khan. "Diana" will open in U.K. theaters in September. A U.S. release date has not yet been set, but Entertainment One, which acquired the American rights to the film last month, said it's planning one for Fall 2013.
