Director Gurinder Chadha came onto the talkRADIO airwaves for a chat with Paul Ross this morning.
The director, who oversaw the 2002 box office smash Bend It Like Beckham, has directed a new film called Viceroy's House.
Starring Hugh Bonneville and Gillian Anderson as Lord and Lady Mountbatten, it tells the final days of the transfer of power to establish Indian Independence in the Partition of 1947.
Chadha, who has roots in the region which is now Pakistan, described the legacy of Partition - and the horrors it witnessed.
She told Paul: "The thing is, 14 million people became refugees over night. That’s the biggest human migration of refugees.
"The horror for me in making this film – which opened in England recently, Australia and Europe and everywhere - is very few people know Partition even happened.
"For me, I’ve been able to shine a light on that, but also tell the story of what happened in the last days of British reign and how it came about."
She also explained why there will never be a sequel to Bend It Like Beckham.
"I can’t do another Bend It like Beckham. That was it – very sweet and perfect. That’s what it was.
"I’d rather work on other things. I’ve got a lovely new film in the works, which in some ways is an echo of that film.
"This one isn’t about football or Beckham, it’s more about Bruce Springsteen. The Boss, I’m a huge fan, it’s been a dream come true to work on this film."
Viceroy's House is now available on Blueray and DVD.
