Like its central character, Alice Walker's Pulitzer Prize-winning novel "The Color Purple" has had a long journey. Published in 1982, this lyrical story of a poor Black woman's eventual triumph over an abusive husband and a seemingly uncaring world became a movie directed by Steven Spielberg in 1985, and then a Tony Award-winning Broadway musical in 2005. And here it is, transformed again: a new movie, based on the stage musical but featuring some new songs, directed by filmmaker/musician Blitz Bazawule.
