The role of Christopher Smith/Peacemaker’s (John Cena) BFF and sidekick was originally played by Chris Conrad, who is probably best-known as Johnny Cage in 1997 film Mortal Kombat: Annihilation. (At the very least, Conrad is best-known for the role among this crowd; Peacemaker and Mortal Kombat are both Warner Bros. IP.)

Cena, 48, who recently revealed his plans to retire from professional wrestling, portrays the titular character of the HBO series. He first appeared as Chris Smith in Gunn's 2021 film, Suicide Squad. Gunn reportedly wrote the script for the series while filming the movie.
