Robert Pattinson has gone more for some unusual movies outside the Twilight franchise, such as Cosmopolis and Remember Me. He’s currently got another film with Cronenberg in the works now (Map To The Stars) and one with Werner Herzog (Queen of the Desert). Now he’s planning to add The Lost City of Z, starring alongside Benedict Cumberbatch.

The film will be directed by James Gray, based on David Grann’s book about doomed Amazon explorer Colonel Percy Harrison Fawcett (Cumberbatch). Screen Daily’s print issue (via TheWrap) says that Pattinson is now on board. There’s no news on who he will play. Some are suggesting he’ll be Fawcett’s son, who also went on expeditions with him, although he seems a little close in age to Cumberbatch for that.

Here’s a few more details about the book: ‘In 1925, Fawcett ventured into the Amazon to find an ancient civilization, hoping to make one of the most important discoveries in history. For centuries Europeans believed the world’s largest jungle concealed the glittering kingdom of El Dorado. Thousands had died looking for it, leaving many scientists convinced that the Amazon was truly inimical to humankind. But Fawcett, whose daring expeditions helped inspire Conan Doyle’s The Lost World, had spent years building his scientific case. Captivating the imagination of millions around the globe, Fawcett embarked with his twenty-one-year-old son, determined to prove that this ancient civilization—which he dubbed “Z”—existed. Then he and his expedition vanished.’
