The film features Alia's character married to a Pakistani army officer, which will be played by Vicky Kaushal.
When asked how different will she be in "Raazi", Alia told reporters, "Very different, I hope, because it is an extremely different film. It is the first time I am doing a period film.
"It is based on a true story and it is for the first time I am doing a true story. So I am very excited. I hope people like it."
The film is scheduled to be released on May 11.
