Trivia: Aside from Romita, Smith, and Kirby, there are a TON more homages in the movie to many of the creators involved with the Daredevil comic in the past. (Frank) Miller, the gritty writer who wrote some of DD's best stories, was mentioned in the courtroom. (Stan) Lee, the legendary figurehead of Marvel was also discussed in Foggy and Matt's conversation in their office. And (Joe) Quesada, the artist in Kevin Smith's great Marvel Knights run, was also discussed somewhere.
Trivia: For a number of years, a sequel was considered, with director Mark Steven Johnson and star Ben Affleck expected to return. Kingpin actor Michael Clarke Duncan also expressed an interest in playing his character again. However, the sequel never materialized, in part due to the failure of the spin-off film "Elektra", and in part because Affleck had decided he didn't want to do another big-budget superhero film at the time.
