Gyllenhaal and Biel could get Nailed
The film tells the story of a receptionist who is accidentally shot through the head with a nail gun, after which she experiences bizarre sexual urges.
She then decides to fight for the rights of people who have suffered odd injuries - but along the way meets a congressman who takes advantage of her newly-discovered passions.
Neither star has signed on for the picture as yet, but Three Kings director David O Russell is attached as the director and co-writer, alongside Kristin Gore - daughter of politician and An Inconvenient Truth presenter Al Gore.
Meanwhile, Gyllenhaal can currently be seen on the big screen opposite Walk The Line actress Reese Witherspoon.
The pair - who are also widely rumoured to be a couple in real life - appear in political thriller Rendition.
