James Gunn wrote the entire first season in 8 weeks during COVID quarantine out of pure boredom, not actually believing the series would ever get picked up.
James Gunn added post-credits scene to each episode as a way to reward fans who always watch to the end of the closing credits.
Eagly is voiced by Dee Bradley Baker, who had previously voiced Sebastian the rat in O Esquadrão Suicida (2021).
When asked how they matched the bloodstains on Peacemaker's uniform in the opening of Episode 1, James Gunn is pretty certain they just used the same one from the end of The Suicide Squad.
The series is set in the town of Evergreen, in Charlton County, Washington. Charlton Comics owned the characters Peacemaker and Judomaster before DC acquired the rights in 1983.
