Development Hell: Daredevil: End of Days, a miniseries depicting the hypothetical deaths of Daredevil and his "biggest secret", was in development since at least 2009. Thankfully, the series is finally being released starting late 2012.
The film:
Executive Meddling: Why the theatrical version was met with a mixed reaction, but the director's cut was more warmly received. Fox smelled potential spin-off with Elektra, so an entire subplot concerning Matt Murdock's "lawyer by day" persona (with his case eventually leading him to the Kingpin) was removed completely. His internal struggle with his vigilante justice clashing with his faith additionally take a backseat to increased screen time for Elektra and their love angle, and the film cut down on the intended Darker and Edgier tone. As a result upon its release, Daredevil nearly became the first film to not cross the $100 million domestic barrier after a $40 million opening, and Elektra completely tanked. Thankfully, the director's cut Set Right What Once Went Wrong.
Fake Nationality: The Greek-American Elektra Natchios is played by very not-Greek Jennifer Garner.
Old Shame: Ben Affleck does not look back on this experience fondly, stating that wearing a costume was "a source of humiliation".
Romance on the Set: Affleck was still involved with Jennifer Lopez and Garner with Michael Vartan at the time, but after those relationships ended, Affleck and Garner became happily married with children.
