Assuming Josh Brolin will play Hal Jordan, or even if another actor around his age is cast in the role instead, I suspect this means that Lanterns intends to adapt the emerald ring-slinger’s Parallax arc.
To be clear, I’m not saying that I don’t have any concerns about Josh Brolin play Hal Jordan, with that alleged casting update being shared by Nexus Point News.
So in that sense, I could understand why DC Studios would want someone like Josh Brolin to play Hal.
