Three new actors have joined the cast of Superman Legacy, the film that will bring in the live-action revival of the DC Universe. They will each be portraying a character with a long history in comic books. Edi Gathegi will play Mister Terrific, Nathan Fillion will play a Green Lantern, and Isabela Merced will play Hawkgirl.

The 2025 film, written and directed by James Gunn, has already cast Rachel Brosnahan from The Marvelous Mrs. Maisel as Lois Lane and David Corenswet from The Politician as Clark Kent. It will chart the road for the new DC Universe that the Guardians of the Galaxy director is creating alongside co-chair and CEO of DC Studios Peter Safran when production begins in January 2024.

Who is Nathan Fillion?

Nathan Fillion was born in Edmonton, Alberta, Canada, on March 27, 1971. He has an older brother named Jeff and is the son of retired English teachers Cookie (Early) and Bob Fillion. His mother has English, German, Finnish, and Norwegian ancestry, while his father is of French-Canadian background. He studied at the University of Alberta, Concordia University College of Alberta, and Holy Trinity Catholic High School in Canada.

Fillion’s first regular role was as Joey Buchanan in the daytime soap opera One Life to Live, for which he was nominated in 1996 for a Daytime Emmy Award. After three seasons, he departed the show in 1997. He made brief cameos in the late 1990s movies Saving Private Ryan (1998) and Blast from the Past (1999). Additionally, Fillion appeared as a guest star in the 1997 films Das Bootie, Mama’s Got a Brand New Bag, and Starcrossed.

The second season of Two Guys, a Girl, and a Pizza Place (1998), in which he played Johnny Donnelly opposite Traylor Howard, Ryan Reynolds, Richard Ruccolo, and Suzanne Cryer, was his biggest break up to that point.

After “Two Guys” finished in 2001, Fillion debuted as Captain Malcolm Reynolds in Joss Whedon’s Firefly (2002), which garnered him critical praise and a sizable cult of admirers. Sadly, the program was abruptly discontinued in late 2002. Furthermore, he appeared in a few episodes of the two short-lived TV series Miss Match (2003) and Pasadena (2001) as Rev. Glenn Collins and Adam Logan, respectively.
