Octavia Spencer is earning major buzz for her powerful role in Black or White, and we've got an exclusive peek at the racial drama.

In the clip, watch the Oscar winner, who plays a grandmother fighting Kevin Costner for custody of their shared granddaughter, give an impassioned speech to her recovering crack addict son (Andre Holland) about stepping up to take responsibility for his child.
Black or White, which also stars Anthony Mackie, takes an unflinching look at race and prejudice through the lens of a custody battle between two grandparents — one Black, one white — for their biracial grandchild.
Black or White opens nationwide on January 30.
