Why Does the Series Centre on Captain Pike?
Strange New Worlds is a spin-off built around Captain Christopher Pike, a character introduced in Star Trek: Discovery. Anson Mount plays Pike in every season, which makes him the anchor of the series.
Because the roster changes between seasons, a single cast list can be misleading. Readers who compare how other series present their casts can consult Cast of Doctor Who.
Which Sources Support These Cast Details?
The details here draw on credits listings, IMDb, Metacritic, Memory Alpha, Screen Rant and TrekMovie, along with a 2021 panel report. Memory Alpha is a community-edited wiki, so its entries may lag behind official announcements.
Episode counts and release dates vary across these sources, and the differences are noted where they affect the cast details. Official Star Trek and Paramount+ pages remain the main reference for current cast and season status. For a comparison with another series’ season-by-season roster, see Cast of Manifest (TV Series).
