Jason Momoa tries to avoid "another needless war" in the trailer for the upcoming Apple TV+ series Chief of War. The new show explores "the unification and colonization of Hawai'i from an indigenous perspective," according to a press release. In the trailer, Ka'iana (Momoa) attempts to protect his family and unify the islands amid Western colonization. "If this island is divided," he says in the preview. "This kingdom will fall." As the teaser continues, viewers learn he does not want to "lead this family into another needless war." Momoa co-created Chief of War with Thomas Pa'a Sibbett. He also wrote the script and serves as an executive producer on the show, which spans nine episodes. The first two arrive on the streamer Aug. 1.
