Elizabeth Banks is going from the world of adult films to the White House.

The actress, who recently wrapped shooting Kevin Smith's Zack and Miri Make a Porno, is in final negotiations to portray Laura Bush in W, Oliver Stone's biopic on the life and presidency of George W. Bush.

The Hollywood Reporter says Josh Brolin already is on board to play Bush in the biopic, which begins shooting in late April in Shreveport, La.

Stone wrote the screenplay with his Wall Street co-writer Stanley Weiser.
