Christian Mingle the Movie – new romantic comedy starring Party of Five's Lacey Chabert

Christian Mingle the Movie is heading to theatres this October – and no, it's not an advert for the popular dating website, says director Corbin Bernsen.

The romantic comedy stars Party of Five's Lacey Chabert as 30-something non-believer Gwyneth Hayden who turns to ChristianMingle.com after years of fruitless dating.

Kids of the 90s will remember Chabert as Claudia Salinger in Party of Five. She also starred as Gretchen Wieners in the 2004 movie, Mean Girls, and has also voiced several popular animation series, including The Wild Thornberrys and Family Guy.

In Christian Mingle the Movie, her character finds more than romance when she meets her Mr Right (Jonathan Patrick Moore) in the handsome, churchgoing Paul Wood.

The trailer – scroll down to watch – promises lots of light-hearted moments as Gwyneth pretends to be a Christian to bag Paul.

But getting to know him stirs some unexpected soul searching when Gwyneth begins to question whether the Christian faith really does have something to it.

The movie has been made by Home Theater Films in partnership with ChristianMingle.com but Bernsen was keen to stress on his Facebook page that it is not an ad or paid promotional piece for the dating website.

"One of my first jobs is to let everyone know that this is a pure, straight up romantic comedy," he said.

"They have been incredible partners and friends in allowing us to use their name and play an integral role in the film, but one of the first rumours I want you to help me dispel is that this is a commercial for them."

That aside, the website and trailer for the film just launched last week and Bernsen could hardly contain his excitement as he shared the news with "great pride and joy".
