HBO’s upcoming DC Studios series “Lanterns” debuted a new trailer at San Diego Comic-Con, offering the longest look yet at the eight-episode mystery. The show follows veteran Green Lantern Hal Jordan, played by Kyle Chandler, and his protégé John Stewart, portrayed by Aaron Pierre. The trailer shows the duo investigating a murder in a small Nebraska town, but the action soon expands into space. Notably, Sinestro makes an appearance, and the trailer also features a shape-shifting Manhunter on the loose. Additionally, a cameo from Guy Gardner is included. The series premieres on HBO on August 16. Earlier footage had focused on the Earth-bound investigation, but this trailer reveals larger cosmic threats. The panel at Comic-Con generated excitement among fans for the DC Universe series.
