Frank Grillo hints that the white hair he had as animated Rick Flag Sr. in "Creature Commandos" could be coming to the live-action DC universe.

Overview

  • The premiere replaces Season 1’s Justice League cameo with the DCU’s Justice Gang, cleanly aligning the series with James Gunn and Peter Safran’s rebooted continuity.
  • Season 2 launches an alternate‑Earth storyline that doubles as character exploration and DC deep‑cut lore, including a Rainbow Creature Easter egg.
  • Frank Grillo returns as Rick Flag Sr., now leading A.R.G.U.S. and pursuing Peacemaker while probing an interdimensional threat linked to portal tech.
  • Critics received episodes 1–5 only, with cast and Gunn teasing major surprises and a high‑profile cameo in the tightly held final three installments.
  • Early reviews are strong (98% on Rotten Tomatoes, 78 on Metacritic), and Gunn says HBO raised no objections to the season’s explicit adult content.
