This just in-
Nathan Fillion has joined the cast of the upcoming James Gunn written-and-directed film, “Superman: Legacy.” He’s not just ‘appearing,’ either. He’ll FINALLY be taking on the role fans have wanted him to play for years, Green Lantern. Fillion will be portraying Guy Gardner, one of the many DC Comics characters to carry the ring.

Other casting news included Isabela Merced (“Dora and the Lost City of Gold”) as Hawkgirl, and Edi Gathegi (“X-Men: First Class”) as Mister Terrific.
These actors join the already announced cast of David Corenswet (“House of Cards“) as Kal-El / Clark Kent / Superman, and Rachel Brosnahan (“Marvelous Mrs. Maisel“) as Lois Lane.
