"Game of Thrones" star Jason Momoa has signed on to play a lead role in Netflix's latest original series "Frontier." According to The Hollywood Reporter, he will play Declan Harp, "an ambitious, confident, charismatic and untamed man with a reputation for being a ruthless trader, driven by lust and revenge."

"Frontier" takes place in the late 18th century during the North American fur trade. Told from several different perspectives, the series imagines a brutal world where business went hand-in-hand with violence. Additionally, the show will examine the tense relationship between the Native people and the European settlers.

Momoa will join Landon Liboiron, Alun Armstrong, Allan Hawco and Zoe Boyle, who were previously announced as stars for the series. Peter Blackie and Rob Blackie created the series. Jeff Fierson and Brad Peyton are attached as producers, with Alex Patrick and John Vatcher executive producing. It will shoot this month in Newfoundland, Nova Scotia, Ontario and Cornwall, England.

In addition to "Frontier," Momoa is also rumored to appear as Aquaman in Warner Bros.' upcoming "Batman v Superman: Dawn of Justice."

"Frontier" is scheduled to air on Discovery and stream on Netflix in 2018.
