Cate Blanchett is attached to star in Joe Wright's upcoming "Indian Summer," the big-screen adaptation of Alex von Tunzelmann's book of the same title.

Von Tunzelmann's story chronicles the final days of Britain's colonial rule in India, as Lord Mountbatten is sent to watch over the transition of power to Jawaharlal Nehru.

Variety reports Blanchett will play Lady Edwina Mountbatten. William Nicholson, whose credits include "Gladiator" and "Elizabeth: The Golden Age," wrote the script.

Oscar winner Blanchett was last seen in "The Curious Case of Benjamin Button." She is currently filming "Robin Hood" for Ridley Scott. Wright last directed "The Soloist."
