Anthony and Joseph Russo, who have been key creative members of the Marvel Cinematic Universe, are now bringing a new show to Quibi documenting the decades-long rivalry between Marvel and DC.

Quibi, the mobile TV subscription startup founded by Jeffrey Katzenberg, greenlit Slugfest, a documentary series executive produced by the Russo Brothers, whose directing credits include a string of hits for Marvel: Avengers: Endgame, Avengers: Infinity War, Captain America: Winter Soldier and Captain America: Civil War.

Slugfest is inspired by Reed Tucker’s book Slugfest: Inside the Epic, 50-Year Battle between Marvel and DC. The docu-series will chronicle the growth of comic books as a new American art form, following the rise of the two companies that went on to become comics-publishing and Hollywood powerhouses.
