The film boasts a formidable cast: alongside Worthington, Neeson, and Fiennes, the ensemble includes Gemma Arterton as Io, Mads Mikkelsen as Draco, and Alexa Davalos as Andromeda. The visual effects by Cinesite, MPC, and Framestore bring the world of Greek myth to life, from the serpent‑haired Medusa to the towering Kraken.
