While it remains to be seen how Karen's relationship with Matt Murdock (Charlie Cox) plays out on the show, Karen was the longest-running love interest for the blind attorney/costumed vigilante in the Marvel comic books. Marvel legend Stan Lee created the character, who debuted in 1964 as a secretary at Matt Murdock and Foggy Nelson's law firm, before she eventually learned about Matt's double life. Ellen Pompeo portrayed Karen Page in the 2003 Daredevil feature.
Take a look at the official press release below for Marvel's Daredevil.
Best known for her resonant work in True Blood, Deborah Ann Woll will play Karen Page, an enigmatic young woman whose quest for justice sends her crashing into the life of Matt Murdock, irrevocably changing his war for a better tomorrow against the forces of evil in Hell's Kitchen.
"Deborah Ann Woll is fiery, self-assured and inspires those around her--all words that perfectly describe Karen Page. It's through Deborah Ann's nuanced portrayal that we see just why Karen is not only important to Matt Murdock, but is a central figure in the war for the soul of Hell's Kitchen."
Marvel's Daredevil follows the journey of Matt Murdock, who was blinded as a young boy but imbued with extraordinary senses, now fighting against injustice by day as a lawyer, and by night as the super hero Daredevil in modern day Hell's Kitchen, New York City.

As you can see in the press release above, despite confirming the characters played by every other actor and actress on the series, Marvel still has not revealed who Rosario Dawson will play. There has been speculation that she will play Elektra ever since she joined the cast in June, but, until we hear anything official from Marvel, we'll have to keep playing the guessing game.
