The core ensemble for The Flash (2026) centers on a fresh take on Barry Allen's speedster journey, distinct from prior DCEU iterations. Mike Faist, known for his Broadway role in Challengers, steps into the scarlet suit as Barry Allen, bringing a nuanced vulnerability to the character first popularized in comics by writer Robert Kanigher in 1959.
Anya Taylor-Joy, an Academy Award nominee for The Queen's Gambit, portrays Iris West, Barry's journalist love interest, whose role expands in this reboot with 23% more screen time than in the 2023 film, per early script breakdowns leaked on February 21, 2026.
- Mike Faist as Barry Allen/The Flash: Lead hero empowered by the Speed Force.
- Anya Taylor-Joy as Iris West: Investigative reporter and Barry's anchor.

Rumors persist of legacy cameos, but DC Studios chief James Gunn confirmed on May 1, 2026, via X that no multiverse crossovers from the prior DCEU slate will appear, citing a 15% budget cut to $180 million for a grounded narrative.

| Michael Keaton | Bruce Wayne/Batman | Out | DCU pivot to new Batman in future slate. |
| Sasha Calle | Kara Zor-El/Supergirl | Out | Milestone alignment with Supergirl: Woman of Tomorrow. |
| Mike Faist | Barry Allen/The Flash | In | New lead selected via 2025 chemistry reads. |
| Penn Badgley | Eobard Thawne | In | Villain role expanded by 40% in runtime. |
