Based on the Dan Brown thriller of the same name, "Lost Symbol" finds protag Robert Langdon summoned to Washington, D.C., where he begins decoding the symbols of the Freemasons....says Variety HERE. No word on whether Tom Hanks will reprise the Langdon role he played in THE DaVINCI CODE and ANGELS & DEMONS, although he's expected to do so. Steven Knight (SHUTTER ISLAND, VOYAGE OF THE DAWN TREADER ) will adapt. Notably, the Variety piece makes no reference to Ron Howard's involvement. Although, honestly, nearly anyone could step into his shoes.
