Trigger warning: the following clip contains scenes of violence.

This advertisement from UK charity, Women's Aid shows actress Keira Knightley suffering shocking physical abuse from her partner. The disturbing ad was directed by Joe Wright who has already made Pride and Prejudice and Atonement with Knightley.

"I wanted to take part in this advert for Women's Aid because while domestic violence exists in every section of society we rarely hear about it," Knightley told UK newspaper The Guardian. "Domestic violence affects one in four women at some point in their lifetime and kills two women every week."

According to the World Health Organisation's first international study into domestic violence, 35 per cent of women worldwide have experienced sexual violence, most often perpetrated by a partner. Nearly 30 per cent of women worldwide have suffered physical and/or sexual violence at the hands of their intimate partner.

According to The 2005 Personal Safety Survey conducted by the Australian Bureau of Statistics, 1,135,000 women, (15 per cent), have experienced violence at the hands of their previous partner and 16,100 have suffered violence from their current partner. One in 3 Australian women over the age of 15 will report physical or sexual violence at some time in their lives. One woman a week is killed in Australia by a current or former partner.
