R-Pattz Joins Benedict Cumberbatch In 'Lost City Of Z'
However, it is currently unknown who Pattinson will play in the film...
The film - which is being directed by James Gray - is based on the novel by David Grann, and will be produced by Brad Pitt's company, Plan B.
Set in the 1920s, it tells the story of English solider-turned-explorer Colonel Percy Harrison Fawcett - who after becoming obsessed with the Amazon, goes on a final self-funded expedition with his son to find a lost city.
However, the pair never return from the trip.
It is thought Cumberbatch will play the lead role of Fawcett, while it is currently unknown what part R-Pattz will portray.
Director Gray previously told IndieWire that the film would have a "slightly more hallucinogenic feel. Because [the protagonist] went to the jungle and sorta went mad."
Pattinson has no films due for release in 2013, but is due to star in The Rover and Maps to the Stars next year.
