Beacon 23 Season 2 Cast

Beacon 23 is back for Season 2 on the shoulders of an incredible cast headlined by Game of Thrones' Lena Headey. 

The MGM+ sci-fi series jumps back into its unique brand of space-faring action with its second batch of episodes starting their run on April 7. 

Season 2 will be eight episodes long and see much of the first season's stacked cast return, as the series continues its tale of twisted fates told at the edge of the known universe. 

Main Characters & Actors in Beacon 23 Season 2

Lena Headey - Aster Calyx

Leading the charge in Beacon 23 Season 2 is Lena Headey as Aster Calyx. Fans may remember, though, that Heady's character notably died at the end of Season 1; Aster sacrificed herself to take out the mysterious reality-bending Artifact. 

Aster is still expected to appear in Season 2. Upon her death, she relayed a prophetic message to the rest of the series' cast, setting the story on the course of a full-scale military assault.

Headey is best known for her role as Cersei Lannister in HBO's Game of Thrones but has also had major roles in Dredd and Zack Snyder's 300

Stephan James - Halan Kai Nelson

While Halan and Aster butted heads at some point during the series' first batch of episodes, he will take up arms in honor of his fallen friend following her death in the Season 1 finale. 

James's previous credits include Race, Selma, and Chadwick Boseman's 21 Bridges
