Variety announced that Friday Night Lights' Connie Britton has been cast to play Nancy's mom, Marge Thompson, in A Nightmare on Elm Street 2010.
The 42-year-old actress has done mostly TV including 24, The West Wing and Spin City.
I should note that it is unknown if she will be called "Marge" in the remake, but that was the character's name in the original Elm Street.
