Oscar winner Jon Voight has come out fighting to defend his controversial pro-life film Roe v. Wade, a movie about the US abortion law, insisting critics 'know nothing.'

Conservative actor Voight asserted to DailyMailTV that his 'really good' new project will educate many on the subject, which has prompted decades of heated debates and outrage.

The movie, set for release next month, was shot in secret as filmmakers feared backlash from pro-choice activists and has prompted huge outrage on social media.

But Voight, 80, who plays Nixon-nominated US Supreme Court Justice Warren Burger in the film, and writer Nick Loeb have urged critics to stay quiet until they see the movie in theaters.

Voight cited that 'people know nothing' about the real case, but will be schooled by the movie.

'There is so much stuff that has been said about Roe vs. Wade, this decision of the Supreme Court in the 70s,' he explained.

'Really people are talking about it and getting excited and upset but they know nothing about it.

'Thank God somebody said let's make a movie about it and show all the aspects.

'The script was loaded with information that I never heard before. It is going to be exciting for people to see.'

In 1973 the US Supreme Court ruled it was a constitutional right for women to have access to safe and legal abortion.

At the time, the decision was met with a great deal of controversy with some lawmakers calling the ruling 'judicial activism', rather than constitutionally ethical.

But today, a Planned Parenthood study found that 72 percent of Americans wholeheartedly agree with the legalization of abortion. However, fierce opposition still remains, particularly in southern states.

Voight added that he is not fazed by the 'furor' from civil rights groups, campaigners and religious sects, saying: 'This moment - it is the tenure of the times that there is a lot of emotion and not an awful lot of scholarship - looking into things and finding the truth.

'So the thing is to encourage everybody to look for the truth.

'This will help. And that is why I did it. I said this is going to help. We will all go to school a little bit. Hopefully it will be entertaining too. There are some very good actors in it.'

Voight's comments were bolstered by the film's writer and co-director Nick Loeb, who refuted claims that film is 'right wing propaganda.'

He vigorously defended his portrayal of Planned Parenthood founder Margaret Sanger as a 'racist'.

'Her first project was called the negro project - her concept to reduce the number of Afro Africans, she was eugenicist,' he said.

'She wrote about it in her autobiography about how she spoke at KKK rallies.'

He complained that 'over 150' mostly negative reviews have been penned about the movie, adding: 'A lot of people do not want to hear the truth, they do not want to know the real story, people are afraid of it and twisted.'

Loeb asserts that the film is neutral, adding: 'We as producers and directors did not take a position. We wrote the characters as they were in real life.'

'If people want to protest against the truth, they do what they want to do. Everything in the movie is 100 percent accurate.'

Voight, the father of Angelina Jolie, insisted the film should be critiqued only after viewing it so that people have a balanced argument.

'People are expressing themselves to it without knowing what it is,' he said.

'It was the same thing with the court decision in the first place. They did not know what it meant...

'So everybody gets on the same page, and then we can start saying, ''here is what I feel, here is what you feel.'''

Voight, who won the Best Actor Oscar for Coming Home in 1978 and has been nominated for four more, added that he picks roles now only on subjects that have 'truth' and 'resonate' with him.

He said: 'I am looking for stories, and if I think there is some truth to something, a good story and a part for me, I will be tempted to go that way.

'That is what I base it on. I do not have any prejudgments. When I see the piece I know if it resonates with me.'

The film's trailer has provoked huge reactions since its release a month ago.

Facebook has reportedly refused to authorize ads promoting the movie because the social media network considers the film a political ad. The producers wanted to buy advertising on Facebook

But the firm said the ad did not align with its new 'issues of national importance' guidelines, according to Breitbart

Writer Loeb also has a role, as Dr Bernard Nathanson, who ran one of the largest abortion facilities in the world before becoming a pro-life activist and narrator of the controversial 1984 movie The Silent Scream.

Loeb is pro-life and is famously involved in a legal battle with ex-girlfriend Sofia Vergara, who stars as Gloria Pritchett in Modern Family, over frozen embryos the former couple produced.

The 27th annual Movieguide Awards, which honor movies and TV series that are 'both well-made and uplifting,' took place at the Universal Hilton in Los Angeles that will air on Hallmark Channel later in the month.
