Brad Pitt's voice is usually identified with movies such as "Troy," "Ocean's Eleven" and "Twelve Monkeys" — not a six-hour documentary on global health.
Starting tonight on PBS and ending Thursday (check local listings), Pitt will narrate six hour-long episodes of "Rx for Survival: A Global Health Challenge," which follows health-care workers and researchers struggling to contain disease among the world's poor.
"I've been involved with the issue of poverty — I've been studying it for about a year and half now," Pitt told The Associated Press in a phone interview Monday from Calgary, Alberta. "I think one of the major causes of that is health, global health."
Pitt has made several trips to Africa in the past two years, including one in July to Ethiopia, where his "Mr. & Mrs. Smith" co-star Angelina Jolie adopted her daughter, Zahara.
