Despite reports that Indian Summer had been given the green light by the Indian government it has now been announced by Variety that the film has been canceled due mainly to budget constraints. Below is what director Joe Wright had to say, via BBC News.

Wright told Variety there had been creative differences between the film’s producers and the Indian government.
“We were in between a rock and a hard place,” he said.
“The Indian government wanted us to make less of the love story while the studio wanted us to make more of the love story.”
