Jennifer Garner wore colored contacts for the role of Elektra. Her natural eye color is brown.

The dead man with the pen in his forehead after Bullseye killed him for his motorcycle is writer/artist Frank Miller.

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.

There is a funny scene in between the credits of Bullseye in the hospital, so keep watching when the credits roll.

Ben Affleck was originally supposed to play Bullseye and Colin Farrel was going to play Daredevil, but their roles were changed at the last minute.

Ben Urich, the reporter who works out Daredevil's identity, is one of the star reporters of the Daily Bugle, Spiderman's working place.

Just a bit of Marvel triva. Ben Urich's nephew Phil became the 4th, heroic Green Goblin in the Spider-Man comics.

The braille charm Murdock finds on the rooftop after he leaves the coffee shop reads "Elektra" spelled perfectly with the first E capitalized followed by lower case letters.

John Romita, the boxer Matt Murdock's father has his last fight with, is the name of an artist and his son who regularly draw for Marvel Comics.

When Matt and Elektra are walking around on the roof, right before Matt 'sees' her in the rain, the director has Elektra in a red dress, which is a nod to Elektra's real red costume in the comics.

When Matt's father is being told that all his former fights have been arranged in his behalf, listen to the names he's been told. Sweeny talks about 'Millar' and 'Bendis', a reference to Mark Millar and Brian Michael Bendis, two red-hot Marvel comic book scribes.

The Kingpin is actually an enemy of Daredevil and Spider-Man.

The comics' Daredevil was for a long time the only superhero who actually knew his buddy Spiderman's secret identity (thanks to his extraordinary senses, of course).

Kingpin is black (unlike the comics) because all the white actors (all of them professional wrestlers) who auditioned for the role were not deemed good enough.

The first time Colin Farrell has been able to use his real Irish accent in an American movie.

Growing up, both director Mark Steven Johnson and star Ben Affleck were fans of the Daredevil comic books.

In the beginning credits, when the actors' names change from Braille to Roman, each series of Braille dots symbolize the corresponding letters from the Roman alphabet.

At the beginning of the movie, the adult Matt Murdock turns on his answering machine and a girl is on breaking up with him. The girl on the machine is Colin Farrell's (Bullseye) sister.

When young Matt Murdock stops the guy from walking into the street, the man is Stan Lee.

The forensic specialist who shows Daredevil's baton to Ben Urich has the name "Kirby." This is a reference to a famous comic book artist. The specialist is also played by Kevin Smith, comic afficionado and creator of Clerks and Dogma, among others.
