A superhero vigilante named Green Angel is hidden in the background of the 2023 thriller film, Missing. The film was directed and written by Will Merrick and Nick Johnson, based on the story by Sev Ohanian and Aneesh Chaganty. Missing stars Storm Reid as June Allen, a teenage girl whose mother, Grace Allen, goes missing while on vacation with her boyfriend, Kevin. While it's not a sequel, the film exists in the same universe as Merrick and Johnson's previous films, Searching and Run. There are many Easter eggs connecting the films, including David Kim from Searching at the beginning of Missing.
