Quick Summary

In episode four of HBO's series "War," Sienna Miller's character, glamorous actress Carla Duval, kisses Archie Renaux's character Johnny Warren, a young lawyer secretly working against her interests. This kiss occurs as Johnny arrives to finalize divorce documents with Carla, unaware that he is leaking confidential information to her ex-husband’s legal team. The episode reveals that Morgan Henderson (Dominic West) is hiding assets worth billions, making his $110 million settlement offer misleadingly low compared to what Carla deserves. Both Miller and Renaux suggest their characters are acting on emotional vulnerability rather than rational decision-making.

In HBO's "War" series, Sienna Miller's character Carla Duval engages in a scandalous kiss with Johnny Warren (Archie Renaux) at the end of Episode 4. This episode aired on October 23, 2026, and is now available to stream on HBO Max. The surprising moment occurs when Johnny visits Carla's home to persuade her to sign divorce papers that will escalate her ongoing legal battle with her ex-husband, Morgan Henderson (played by Dominic West).
