Catherine Halsey/Silver
From Halopedia, the Halo wiki
Doctor Catherine Halsey is the creator of the Spartan supersoldiers.[1] Production notes[edit]Catherine Halsey in Halo: The Television Series is portrayed by actress Natascha McElhone.[1] McElhone was originally cast to play both Halsey and Cortana, much like Jen Taylor did for Halo 4, Halo 5: Guardians, and Halo Infinite. However, due to scheduling difficulties caused by the COVID-19 pandemic, McElhone was unable to complete her work as Cortana, so Jen Taylor was brought onboard the project to reprise her role from the games.[2] Gallery[edit]
