VIDEO: Keira Knightley beaten in violent domestic abuse PSA

Keiraknightley_pirates2pr_240 "Pirates of the Caribbean" star Keira Knightley has taken a stand against domestic violence in a two-minute clip that depicts the actress being beaten and kicked by a man.

The ad debuts in movie theaters on April 6, only two months after R&B singer Chris Brown allegedly beat his girlfriend Rihanna before they pulled out of the Grammy Awards.

Knightley's ad for Women's Aid, shot by her "Pride & Prejudice" and "Atonement" director Joe Wright, follows the actress after a day of filming and going home to a man playing her boyfriend. He expresses suspicion and jealousy over her intimate work with a costar and then strikes her till she falls.

As she's down, the man continues to kick her as the words "Isn't it time someone called cut?" fill the screen.

Check out the domestic violence PSA yourself.
