Overview
- Netflix announced the premiere date and released the first trailer and first-look images on Wednesday, Nov. 4, to begin promotion for Trinity.
- The series stars Gugu Mbatha-Raw as Commander Katherine Decker, second-in-command on the nuclear submarine USS Kansas, and Richard Madden as Secretary of Defense Webb Preston, and centers on Decker uncovering a conspiracy tied to global security.
- Jed Mercurio is the creator, showrunner, writer, and an executive producer, with Michael Cuesta directing the pilot and 20th Television and Hat Trick/HTM listed as studios and production partners.
- Coverage disagrees on the season length: some outlets describe an eight-episode order while others say the season was reduced to seven episodes; episodes are reported to run about 60 minutes and filming took place in Vancouver from July to October 2025.
- Mercurio’s return to political thrillers and his reunion with Madden follow high-profile shows like Line of Duty and Bodyguard, which sets strong expectations for critical comparisons and could shape Netflix’s December release slate and audience response.
