The star of new movie 'Gosnell' says the bias against is unlike anything he's seen.

Dean Cain, best known for his role in 'Lois and Clark', plays detective investigating real-life abortionist Kermit Gosnell. In 2013, the notorious abortionist was sentenced to life imprisonment without parole over the deaths of three babies who survived the abortion procedure at his West Philadelphia clinic.

The movie about his case was made on a shoestring budget of $2.3m raised through crowdfunding, but it quickly made back more than what it cost in the first few weeks after it opened on October 12.

To date, the movie has pulled in $2.5m at the box office despite being a limited release running on just 668 screens. 

But it has faced an uphill struggle, with Facebook reportedly blocking adverts promoting the movie and the producers now reporting that hundreds of theaters have dropped the movie from their rosters. 

According to The Christian Post, around 200 theaters dropped the movie after the first couple of weeks. 

Now PJ Media reports that at least 253 theaters have dropped the pro-life movie since it opened on October 12.

Director Nick Searcy blames the Left.

'This movie really exposes something that the Left does not want to report about," Nick Searcy told PJ Media.

'They're basically trying to ignore this movie. They're trying to say that it doesn't exist because they don't want to have a discussion about abortion.'

Cain, speaking to Lifezette magazine, thinks what is happening with 'Gosnell' is unprecedented in the movie industry. 

'I have never experienced anything like this before, but perhaps it's a sign of the times,' he said.

'So many folks have become so polarized these days here in the United States that they instantly demonize anyone with whom they have any disagreement.

'It happens on both sides, and I find it ridiculous.'

Producer John Sullivan agrees that the experience with 'Gosnell' is unusual. He said the movie had been dropped from a 15-screen multiplex even though it was at number six, and a 30-screen theater where it was ranked ninth.

'I can tell you from my experience in 15 years of releasing movies independently, we're in uncharted territories,' he told the Daily Wire.

'It is an impacted fall, no doubt about it, but the fact that we've been dropped from theaters where the movie is the number 6 or number 9 movie is just something you don't see.

'It's hard not to believe it isn't about the content of the movie.'
