Charlie Hunnam, Sienna Miller and Robert Pattinson star in James Gray's period adventure set in the South American jungle.

Director James Gray and the producers of The Lost City of Z have lost an appeal to overturn an R rating for "brief violence" in the film.

The period adventure drama, from Amazon Studios, is set to hit theaters April 21 via Bleecker Street. Gray and Dede Gardner of Brad Pitt's Plan B Entertainment appeared before an appeals panel this week in Los Angeles to argue in favor of a friendlier PG-13 rating.

Joan Graves, chairman of the Classification and Rating Administration, represented the ratings board, which upheld the R rating.

Lost City of Z, which stars Charlie Hunnam, Sienna Miller and Robert Pattinson, tells the true story of a British army officer who ventured into the South American jungle a century ago in search of an ancient civilization.

The movie made its world premiere last fall at the New York Film Festival and is based on David Grann's 2009 best-selling book. Gray wrote the adapted script.
