Since her death in 1970 at age 27, Janis Joplin has been a ubiquitous presence on posters, T-shirts, and classic-rock radio. In Janis: Little Girl Blue, Academy Award–nominated filmmaker Amy Berg culls unseen material, interviews Joplin’s confidantes, and uncovers personal letters to refocus the icon as a human being. Singer Cat Power (aka Chan Marshall) does an uncanny job of re-creating Joplin’s voice in readings from her letters, revealing a more vulnerable character who cycled in and out of addictions and channeled her emotions into art. The dominant voice is Joplin’s own in the resulting portrait that gives us fresh insight into the mighty talent behind famous versions of “Piece of My Heart,” “Cry Baby,” and “Me and Bobby McGee.” A FilmRise release.
