"I am very excited as, for the first time, I am doing action in a film," she said at an event to launch People magazine.
"It's sort of an action film. It's very real but, at the same time, it's very very slick. It is about agents going into Pakistan and getting back India's most wanted man," she said.
While in Gangs Of Wasseypur, Huma worked with stars like Manoj Bajpayee and Nawazuddin Siddiqui, in Vishal Bhardwaj's production Dedh Ishqiya, she is working with stalwarts like Madhuri Dixit, Arshad Warsi and Naseerwuddin Shah.
D-Day, releasing July 19, also features Arjun Rampal, Rishi Kapoor, Irrfan and Shruti Haasan.
Four-film-old Huma feels lucky that she is getting to work with such living legends in her films.
"I am very fortunate because I am one of the newest (actors), but I have already worked with some of the best actors we have of our time, whether it's Manoj, Nawaszuddin or Irrfan, and then Arshad (Warsi), Naseeruddin Shah, Madhuri," she said.
"With each film I feel that my association with some solid actors of our generation is only getting stronger and stronger. I just hope that by being in films, that have such living legends as part of the cast, I only get to learn from them, by watching them and I hope I imbibe something from them," she added.
Huma was recently seen in Ek Thi Daayan opposite Emraan Hashmi that also starred Konkona Sen Sharma and Kalki Koechlin.
