The cast of Girls have shared a powerful video speaking out against sexual assault in the wake of the Stanford swimmer rape case.

Lena Dunham, Allison Williams, Zosia Mamet and Jemima Kirke star in the video urging people to help survivors of sexual assault instead of blaming the victim in the NowThisNews clip, which Lena shared on Twitter on Wednesday.

'I dedicate this to the brave survivor in the Stanford case who has given so much to change the conversation,' the 30-year-old wrote.

Stanford student Brock Turner sparked public outcry when a judge sentenced him to just six months in jail after he was found raping an unconscious woman near a dumpster outside a frat house party. He was convicted of three counts of felony sexual assault.

Despite the ongoing outcry over the 'lenient' six month sentence he received, Daily Mail Online revealed that he is due to be released after just four months – on September 2.

The victim has chosen to remain anonymous, but penned a powerful letter to her rapist about how the attack had affected her life, which went viral.

In it she said: 'He is a lifetime sex registrant. That doesn’t expire. Just like what he did to me doesn’t expire, doesn’t just go away after a set number of years.'

Now, the Girls stars have come together to create the video urging people to 'support, listen, take action' to help survivors of sexual assault.

'We may star on Girls together, but that doesn't mean we always agree,' says Jemima in the video.

'We sometimes vote for different candidates,' says Zosia.

'We have very different views on appropriate undergarments,' jokes Lena.

Jemima then adds: 'But there is one issue that we are in total agreement.'

The video then shares The Centers for Disease Control and Prevention's statistics that 1 in 5 women will be sexually assaulted during her lifetime, and 1 in 4 of those assaults will happen to women under the age of 18.

And in 80 percent of cases, the attacker is someone the victim knows.

Urges compassion: Zosia said the 'default reaction' is to victim-blame

Viral video: Victims are silenced, Lena said

National shame: Victims of rape are doubted and made to feel like it's their fault, the actors say

Given those sobering statistics, 'why is our reaction as a society to disbelieve? Or to silence? Or to shame?' the Girls stars ask.

Zosia says: 'What if we chose to turn toward those in need, instead of away? You have a choice to make things better.'

The Girls actresses then urge people to listen and support victims in simple ways, like offering to hear their story, reach out with a phone call or drive them to medical care or counselling.

Passionate plea: Zosia urges viewers to help change the way society reacts to rape survivors

Even just 'calling out a hurtful remark' can help survivors and change the culture of blaming the victim, they suggest.

'It can even be simply listening,.. just being there makes it better' says Lena.

Allison adds: 'Don't avoid the hard conversation... you already have the power to create a safer, healthier environment for women to come forward.'

Side by side: The actors said they hoped to represent the support that all survivors should be able to find

The video ends: 'And while its just the four of us here right now, we hope to represent the solidarity and support all survivors should be able to find.'

And Lena chimes in: 'Which may be the first time that four white women can accurately represent anything.'

The actors urge people to 'support, listen, take action' to support victims of rape and sexual assault.

'Not because she's someone's daughter, or someone's girlfriend or someone's sister.

'But because she is someone,' they say while holding hands.
