Sharmeen Obaid Chinoy is a documentary film-maker whose 2012 film about acid violence, Saving Face, made her the first Pakistani to win an Academy Award. This year, she is nominated again for A Girl in the River: The Price of Forgiveness, which tells the story of 19-year-old Saba Qaiser, from the Pakistani province of Punjab, whose father and uncle shot her in the face and threw her in a river because she had married without her family’s consent. Because she had tilted her head at the last minute, Saba survived the shooting and managed to get to a petrol station for help. But although her father and uncle were subsequently arrested, Saba came under pressure to forgive them, which under Pakistani law means they would escape further punishment.

How did you come across Saba’s case?
I wanted to tell a story about “honour” killings, from the perspective of somebody who had survived, because almost always victims of “honour” crime die, and it’s very hard then to tell the story, because you never have the perspective of that person and what they went through. So I was searching for a survivor, and one day I read in the newspaper that a girl had been shot and put in a gunny bag and thrown in a river, and survived, and was in a hospital. So I went off to try and find that hospital.

And obviously you did…
Yes, I found her in hospital – it must have been about two days after she had been shot. We got permission from the hospital, and we spent a lot of time speaking to her; you know, she was very open to telling her story because she believed very strongly that she didn’t want anyone else to go through what she had.

She must have been in a great deal of pain, and shock?
She was. She had this extraordinary kind of will though – this defiant will about her, even on day one. And she just took to filming matter-of-factly, as if she was born for the camera. But she never did anything extra for the camera, she was who she was; and you see that as the film progresses, you see her demeanour, the way she reacts, the way she laughs – it’s all very natural.

She was also facing the immensely painful reality of her own family having tried to kill her, and now ostracising her. How common is that situation?
It is a pretty common narrative, because about a thousand women are killed in “honour” crimes in Pakistan every year; and we think the number is much higher because many cases go unreported. The problem with “honour” killing is that it’s considered in the domain of the home. People hush it up: a father kills a daughter, and nobody ever responds, nobody ever files a case. The victim remains nameless and faceless, and we never hear about them. People feel, “if we register a case, it will bring shame to the family”. So this [film] is a way for us to bring it out in the open, to have a national discourse about it, for us to say this is a crime, it has nothing to do with honour; it’s premeditated, cold-blooded murder.

What has the reaction in Pakistan been like?
One of the most encouraging things was that the prime minister made a statement after the [Academy Award] nomination. He said that he would look into this matter and he would work on “honour” killings and he wanted to hold the first screening at his residence. Now, that is a very brave statement to make, it’s also a very forward-thinking statement. And we are now waiting to hear back from the government about a date to hold the first screening; we are hopeful that he will follow through on his statement.

And your view is that a change in law is the fundamental aim?
The thing about “honour” crimes is that there are people who don’t think that it is a crime because people don’t go to jail for it. If you have entire towns and villages where people know of people who have killed their daughters or their wives or their sisters and never been to jail, you will think it is not a crime. As long as people don’t think it’s a crime, they will continue to kill women. The minute people start going to jail, it will act as a deterrent. People will know that there are serious repercussions and that it is a heinous crime. We have to take that first step of sending people to jail.

You’ve made many films, in many different places and circumstances – about Pakistan’s transgender community, about Bangladeshi female peacekeepers deployed to Haiti, about child terrorists. How much has being a female film-maker affected issues such as access, or how people react to you?
I think that I’ve been fortunate to be a female film-maker. It allows me greater access, greater sensitivity in some cases to some of the subjects. I can go into places that men cannot as easily. Being a woman has really been an asset for me, and I don’t think I’d be able to tell the kind of stories that I do if I was a man.

This Academy Award nomination comes in a year when diversity is a huge issue, with some actors and directors planning to boycott the awards. What’s your feeling about that?
I think that the Academy is a reflection of Hollywood. I think that you cannot blame the academy, you have to begin making changes in Hollywood first, and see how many films come out with diverse characters in them, with diverse scripts. It’s only when you bring diversity into Hollywood that you can bring diversity into the Academy Awards. Having said that, if you look very closely this year, there are a number of film-makers from around the world, outside of the foreign-language categories.

As a documentary film-maker, when I’m looking at diversity, I’m not looking at the actors and actresses, I’m looking at my field – and in my field, there is diversity this year. In my category, there’s a film from Pakistan, a film about the Holocaust, a film about Vietnam, one about Ebola and Africa – the diversity’s immense, just in the subjects that are being tackled.

What’s happening in the documentary world? There are great practitioners, but is it sometimes a struggle to get films made?
Yes. But the good thing about documentary films is that you have some major players coming in. Netflix,Amazon, these will all change the way documentary film-makers tell their stories – the experimentation is enormous. In some cases, the genre is taking many more risks than it did before.

How do you feel about your prospects on 28 February?
This is a very competitive year – there are some fantastic films out there, and some fantastic film-makers. You never know until that envelope is opened who’s going to be announced. So I am putting all my energy into getting the Pakistani government and the Pakistani prime minister to make good on his promise. To me, it will be a bigger win if we do manage to at least begin to send people to jail for “honour” killings. That’ll be a much bigger win.

And what news do you have of Saba?
Since the filming stopped, she’s had a son [with the man she chose to be with], and she’s basically hoping to educate him. A donor has come forward to give land to her, so she has land in her own name. She didn’t even have a birth certificate or an ID card, all of that has been processed. She finally has an identity of her own.

The 88th Academy Awards ceremony is on 28 February. A Girl in the River: The Price of Forgiveness is nominated in the documentary (short subject) category. Sharmeen Obaid-Chinoy hopes the film will be shown later this year in communities across the UK where “honour” crimes have occurred
