The government officials are reportedly "assessing" the script to ensure that Nehru's "friendship" with Edwina in the movie is not shown wrongly.

"Filming of Indian Summer, starring Cate Blanchett and Hugh Grant, has been halted while Indian government officials assess the portrayal of Nehru's "friendship" with the last Vicereine. They are thought to have asked to see the script to ensure the plot is not too salacious," British newspaper The Telegraph reported quoting sources from movie production.

Directed by 'Atonement' filmmaker Joe Wright and produced by Universal Pictures, the film reportedly depicts Nehru and Edwina as secret and passionate lovers, which is likely to ruffle feathers in India, the newspaper said.

Starring Oscar-winning Cate Blanchett as Edwina, the movie tells the story of Lord and Lady Mountbatten's return to India in 1947 for the handover and is based on the book 'Indian Summer: The Secret History of the End of an Empire' by Alex von Tunzelmann.

The movie, which reportedly also stars British actor Hugh Grant and depict the last days of Empire in India as Lord Mountbatten hands over power during the summer of 1947 to Nehru, is slated to go on floors early next year. It is slated to release in 2011.

Mountbattens' daughter Pamela has also written about "special relationship" between her mother and Nehru in her memoir 'India Remembered: A Personal Account of the Mountbattens During the Transfer of Power' where she claimed the pair were deeply in love, but their relationship remained platonic.

"While her mother had taken lovers, and that her father had reconciled to it, both her parents and Nehru were a 'happy threesome'," she wrote in her book.
