The series, set to premiere in January 2022, is based on the DC Comics character created by writer Joe Gill and artist Pat Boyette in 1966. “Peacemaker” stars John Cena in the titular role, reprising his character from “The Suicide Squad.” The series takes place after the events of the film and looks at the origin story of Peacemaker, a complicated hero who strives to achieve peace no matter what — even if it means killing people. Created by James Gunn, who also directed “The Suicide Squad,” “Peacemaker” is the first television series to come out of the DC Extended Universe.
In the new footage, Peacemaker shows up to a dinner in a public restaurant with friends in full superhero regalia. “Why are you in your costume?” one asks.
