While it’s been 20 years since Nathan Fillion and Alan Tudyk have flown in the Serenity together, we have still been lucky to see them reunite on several occasions including Con Man, The Rookie, and even with Fillion voicing an E.T. octopus on Resident Alien. Now it looks like the two may once again cross paths in James Gunn’s new Superman film.

It’s now being reported that Tudyk has signed on to an undisclosed role (which everyone is pretty sure will be Brainiac or Plastic Man). That means there’s a good chance he’ll be sharing screentime with Fillion who has already been cast as Guy Gardener. They are both joined by:

  • David Corenswet as Superman
  • Rachel Brosnahan as Lois Lane
  • Isabela Merced as Hawkgirl
  • Edi Gathegi as Mister Terrific
  • Anthony Carrigan as Metamorpho
  • Gabriela de Faría as The Engineer
  • Sara Sampaio as Eve Teschmacher
  • Wendell Pierce as Perry White
  • Skyler Gisondo as Jimmy Olsen
  • Pruitt Taylor Vince as Pa Kent
  • Neva Howell as Ma Kent
  • Beck Bennett as Steve Lombard
  • Mikaela Hoover as Cat Grant
  • Christopher MacDonald as Ron Troupe
  • Nicholas Hoult as Lex Luthor
  • MIllie Alcock as Supergirl

Superman will hit theaters July 11, 2025.
