'Superman: Legacy' Casts Nathan Fillion as Green Lantern, Isabela Merced and Edi Gathegi

"Superman: Legacy" writer-director James Gunn has cast Nathan Fillion as Green Lantern, Isabela Merced as Hawkgirl, and Edi Gathegi as Mister Terrific in the upcoming DC film. The addition of these superheroes suggests Gunn's intention to re-launch the DC cinematic universe as a fully-formed entity. The film will focus on Superman balancing his Kryptonian heritage with his human upbringing, embodying truth, justice, and the American way. The deals for the actors were made two years before the film's scheduled debut in 2025.
