As Cersei Lannister, Lena Headey has endowed Game of Thrones’ resident queen of mean with a sharp tongue, but now the actress is sinking her teeth into a new role, as EW can exclusively reveal the 42-year old will narrate an upcoming Shark Week documentary, Air Jaws: Night Stalker, on the Discovery Channel.

The documentary will revolve around photographer Chris Fallows, shark expert Jeff Kurr, and marine biologist Neil Hammerschlag as they examine the hunting patterns of great white sharks. Air Jaws: Night Stalker will get up close and personal with the creatures of the deep, exploring their ability to stalk prey and ultimately go in for the kill without the presence of any sun or moonlight.

The Emmy-nominated Headey has appeared on Game of Thrones since the show’s first season in 2011. Recent film roles include the genre satire Pride and Prejudice and Zombies (2016), the action epic 300: Rise of an Empire (2014), and Blumhouse Productions’ horror hit The Purge (2013).

Though an air date for Air Jaws: Night Stalker has yet to be announced, the full Shark Week lineup is expected to be released in the coming days. The Discovery Channel’s annual shark-themed programming block begins June 26 at 8 p.m. ET.
