LONDON, ENGLAND (WPIX) -- Keira Knightley is taking a high-profile stand against domestic violence.  The actress has released a shocking new anti-violence public service announcement in Britain.  The release of the ad comes just days before R&B singer Chris Brown is scheduled to be arraigned for attacking his girlfriend, singer Rihanna.

In the two-minute ad for the non-profit group Women's Aid, the actress is on a movie set portraying a women who is accused by her boyfriend of having an affair.

The man punches before slapping her down to the ground, where he brutally kicks her over and over again. The ad ends with the words, "Isn't it time someone called cut?" appearing on the screen.

Knightley said by appearing in the PSA, she hopes she sheds light on an issue that is not often addressed.

"While domestic violence exists in every section of society, we rarely hear about it," she said.

The ad, titled "CUT," was directed by Joe Wright, who directed Knightley in the film "Atonement." The PSA could already be seen on the internet and is expected to be shown on television and in movie theaters in Europe.
