Firth executive produced Mumia documentary

NEW YORK, Oct. 1 (UPI) -- Sundance Channel has announced it acquired "In Prison My Whole Life," a feature documentary executive produced by British actor Colin Firth.

Directed by Marc Evans and written by Evans and William Francome, the film "follows 25-year-old William Francome's investigation into the arrest of Mumia Abu Jamal, famed death-row prisoner and award-winning Black Panther journalist," Sundance Channel said in a news release.

"Francome, born on the day of Mumia's Dec. 9, 1981 arrest (for the killing of a Philadelphia police officer), engages intellectuals, writers and musicians in an effort to expose the truth about justice in America for black activists in general and Mumia in particular."

Featuring interviews with Alice Walker, Noam Chomsky, Mos Def, Snoop Dogg and Steve Earle, the film is scheduled to premiere on Sundance Channel Dec. 8.
