Nathan Fillion will play Guy Gardner, an obnoxious Green Lantern with a terrible haircut, in Superman Legacy, the movie that will reboot both the beloved superhero and the DC Universe on film.

Fillion’s casting was one of a trio of deep-cut heroes confirmed for the movie that DC Studios co-chair James Gunn is writing and directing himself. According to Vanity Fair’s report, the others are Isabela Merced as Hawkgirl and Edi Gathegi as Mister Terrific. The three actors join David Corenswet as Superman and Rachel Brosnahan as Lois Lane.
