Weekend Movie Forecast: Brüno or Humpday

The three day Zaire '74 concert was supposed to coincide with The Rumble in the Jungle between George Foreman and Muhammad Ali, but when the bout was delayed after Foreman got cut during training, the concert went on as scheduled anyway. The documentary Soul Power chronicles the sights and sounds of those three days. Joe Morgenstern at the Wall Street Journal writes, "Period pieces can be marvelous or musty, depending on the period, as well as the piece. Soul Power is marvelous, and no wonder—among the performers in this concert film are James Brown, B.B. King, Bill Withers, Miriam Makeba and Celia Cruz, all at the peak of their powers."
