During the production of Crisis on Infinite Earths, Frank Miller was the writer of Marvel Comics' Daredevil where he finished his long run with the character in issue #191. He went on to work for DC and produced the influential four-issue limited series Batman: The Dark Knight Returns (1986), but was put on hold due to unsuccessfully developing ideas for the story. In 1985, Miller returned to Marvel to resume his role as the writer of Daredevil starting with issue #219. At some point, he fully committed himself into developing The Dark Knight Returns as ideas came to fruition. By the time the Daredevil series reached to issue #226 in 1986, Miller and artist David Mazzucchelli eventually collaborated for the first time and then they collaborated again on the critically acclaimed seven issues #227-233 which eventually titled as Daredevil: Born Again in the collected edition. Both Miller and Mazzucchelli soon left Marvel afterwards. In 1986, editor Dennis O'Neil moved on from Marvel to work for DC again where he helped Miller to edit The Dark Knight Returns.
