Directed by British-Indian Gurinder Chaddha "Viceroy's House" set in 1947 revolves around the story of Partition and the human impact due to it.
"It is a very special film which has taken a lot from me... I have put my heart and soul into it," Huma told PTI about her international debut film.
The film headlined by Hugh Bonneville, Gillian Anderson, Huma and Manish Dayal will see the "Gangs of Wasseypur" actress essay the role of Aalia, a Muslim, falling for a Hindu boy, Jeet (Manish) who works at the Viceroy's House but they are ripped apart as borderlines are redrawn.
"There is a Hindu servant and a Muslim translator who work in that household and the country is burning. It's a very touching topic," Huma says.

Hugh plays the role of Lord Mountbatten, the man charged with handing India back to Indians, and Huma is his Muslim interpreter.
The "Badlapur" actress was fascinated with the story of her international debut film apart from being awestruck with Gurinder's previous films.
"I was very excited to do the film because Gurinder is a celebrated director. Her work has always fascinated me. But apart from that, she is a Punjabi-Indian who is a British citizen, making an Indo-British film about the partition.
Huma says the film will be dubbed in Hindi as well so that it reaches a wider audience during its India release.
"I really want as many people to watch it. We are doing a Hindi dub for it as well because the film is completely in English. It is touring festivals and the film has snowballed into something else. I am thrilled about it."
