With not one, not two, not three, but four Avatar sequels on the way, now comes word of another new addition for the franchise.

Courtesy of Deadline, Game of Thrones’ Brendan Cowell has signed on to play a character called Mick Scoresby. Said character will be the captain of a private sector marine hunting vessel used on Pandora.

Cowell – who Thrones fans will recognise as Harrag – joins a cast that features the returning Sam Worthington, Zoe Saldana, Stephen Lang, Sigourney Weaver, Joel David Moore, Dileep Rao and fellow new additions Kate Winslet, Cliff Curtis and Oona Chaplin.

In terms of plot specifics, very little is known about these upcoming Avatar outings right now. What we do know, however, is that Avatar 2 is set for December 2020, Avatar 3 for December 2021, Avatar 4 for December 2024 and Avatar 5 for December 2025.

To date, James Cameron’s first Avatar is still the highest-grossing movie in history; nabbing a whopping $2.7 billion at the global box office.
