London: Disheartened by the result of the Brexit referendum, popular British filmmaker of Sikh origin Gurinder Chadha is having trouble in focusing on her next project "Viceroy's House" - a film centred on events of India's Partition. Britain voted in favour of exiting the European Union (EU) on Friday. And Chadha, also known for films like "Bend It Like Beckham" and "Bride and Prejudice", feels like it is history repeating itself. She tweeted: “Hard to focus on editing my film on Partition 1947 with such a broken heart in 2016. #history #lessonsnotlearnt #divideAndRule”. The film stars English actor Hugh Bonneville as Lord Mountbatten, the last Viceroy of British India. It also features Gillian Anderson, veteran Indian actor Om Puri and "Gangs of Wasseypur" actress Huma Qureshi. "Viceroy's House" is centred on events of India's Partition. It is an emotional story set in the kitchens and staff of the Viceroy's house. It is produced by Deepak Nayar, Chadha and her husband Paul Mayeda Berges.
