Jena Malone as Carrie Kelly in Batman V Superman: Dawn of Justice

Larry Doherty touched on this one in his picks of the week this week.
Newsarama ran a piece quoting Variety that Jena Malone could be appearing in Batman Vs Superman: Dawn of Justice as Carrie Kelly, aka the Female Robin that appeared in the Dark Knight returns.

Carrie Kelly, who first appeared in Batman the Dark Knight Returns, could be in the heavily Frank Miller influenced Batman vs Superman Dawn of Justice movie.
While, Batman the Dark Knight Returns, could be out of some people’s price range, Carrie Kelly’s first new 52 appearance is an easy scoop at a cheap price.
Carrie Kelly first appears in the New 52 in Batman and Robin #19. Copies of the book are on eBay for under $2.
A real cheap play with great potential.
