The largest iceberg carving ever filmed has been caught on camera for a new movie, called Chasing Ice.

Photographer James Balog likened watching it to seeing "Manhattan breaking apart in front of your eyes", according to the Guardian.

After weeks of waiting, the film makers witnessed 7.4 cubic km of ice crashing off the Ilulissat glacier in Greenland.

Chasing Ice, released in the UK on Friday 14 December, follows James Balog's mission to document Arctic ice being melted by climate change, after initial scepticism about the phenomenon

Want to know more about the film? Its website explains: "Acclaimed photographer James Balog was once a skeptic about climate change. But through his Extreme Ice Survey, he discovers undeniable evidence of our changing planet. In Chasing Ice, Balog deploys revolutionary time-lapse cameras to capture a multi-year record of the world's changing glaciers. His hauntingly beautiful videos compress years into seconds and capture ancient mountains of ice in motion as they disappear at a breathtaking rate.

"Travelling with a team of young adventurers across the brutal Arctic, Balog risks his career and his well-being in pursuit of the biggest story facing humanity. As the debate polarizes America, and the intensity of natural disasters ramps up globally, Chasing Ice depicts a heroic photojournalist on a mission to deliver fragile hope to our carbon-powered planet."
