Never one to shy away from controversy, British documentarian Nick Broomfield (Kurt & Courtney, Heidi Fleiss: Hollywood Madam) takes on the mysterious murders of rap stars Tupac Shakur and the Notorious B.I.G. (aka Christopher Wallace) in 1996 and ’97 respectively. The two men were friendly once but got caught up in a feud between their record labels (Suge Knight’s Death Row Records in Los Angeles and Puff Daddy’s Bad Boy Records on the east coast). A wily and dogged inquisitor, Broomfield cajoles and confronts a variety of witnesses in this 2002 feature, charting a web of intrigue that also involved the LAPD, the FBI, and assorted gangbangers and rogue cops. As the childhood, meteoric career, and last day of each victim come into clear focus, so does the case against those who might have ordered the killings. 107 min.
