HBO and Sky release first look and trailer for “War” starring Dominic West and Sienna Miller

HBO and Sky on Aug. 6 released a first look and trailer for their upcoming divorce drama series “War,” with Dominic West and Sienna Miller starring. The promotional materials highlight a central confrontation between the couple, anchored by the line, “You are the wronged party here,” which appears in the trailer as the pair’s relationship fractures.

The series is described as a divorce drama built around the fallout from a high-stakes marital dispute involving a tech entrepreneur character named Morgan Henderson. Deadline’s report frames the project as a battle between West and Miller’s characters, setting the tone for negotiations, accusations, and escalating conflict as the marriage unravels.

The first look includes trailer footage and promotional photos released by HBO and Sky in connection with the show’s campaign. Deadline reported that the series is being developed for the HBO and Sky platforms, indicating a coordinated release strategy across the two services rather than a single-network rollout.

Deadline also characterized the project’s promotional messaging as one in which both West and Miller appear to be preparing for confrontation. The “wronged party” framing suggests that the series will treat the divorce not as a background event but as a primary engine for dialogue and power shifts, as each side asserts its version of events.

While details about episode count, production timeline, or the specific identities of each character’s role in the marriage were not included in the information released with this first look coverage, the materials released to date establish the show’s genre focus and core premise: a divorce centered on a tech-linked business life and a disputed account of harm.

As with other drama series launches, the trailer and first-look photos are expected to serve as the initial audience touchpoint ahead of a fuller release announcement from HBO and Sky, including information such as premiere date and additional casting or creative credits. For viewers deciding whether to follow the series, the early campaign positions “War” around courtroom-adjacent marital conflict and the shifting narrative control that often accompanies contested divorces.

For West and Miller, the project represents another high-profile screen pairing in a conflict-driven drama. HBO and Sky’s coordinated release of the first look, along with the public-facing promotional line about being the wronged party, indicates the series’ opening narrative will emphasize blame, leverage, and the stakes of separating personal relationships from financial and professional entanglements.
