Screen can exclusively reveal the first trailer for Lars Ostenfeld’s Into The Ice, which will have its world premiere in competition as the opening film of CPH:DOX film festival next month.

The documentary will play in Copenhagen on March 21, two days before the festival officially opens; with the event running until April 3.

The festival has planned its first in-person event since 2019, with the last two editions having been moved online due to the pandemic.

Into The Ice sees Ostenfeld travel to Greenland with three of the world’s leading glaciologists, to see just how fast the ice sheet is melting, and to understand the consequences of climate change.

The film is produced by Malene Flindt Pedersen for Denmark’s Hansen & Pedersen.

CPH:DOX artistic director Niklas Engstrom described it as “part adventure movie, part scientific exploration, part call to action” when it was announced as the festival’s opening title earlier this month.

The film is produced by Malene Flindt Pedersen for Denmark’s Hansen & Pedersen.

Ostenfeld has previously worked as a TV producer, including for 2020 wildlife series Wild And Wonderful Denmark.

The full CPH:DOX programme will be unveiled on March 1.
