Director Ali Abbas Zafar, who is basking in the success of his latest release "Sultan," has expressed his desire to make a war film. "I am dying to make a war film. I would also like to make a horror film but a war film is something that is definitely on my mind," Ali told PTI.

Ali made his directorial debut with Katrina Kaif starrer "Mere Brother Ki Dulhan". He then made "Gunday" with Ranveer Singh and Arjun Kapoor. His recent film with Salman Khan has been a blockbuster. All his films were produced by Yash Raj Films and his next film will also be with them.

"I am writing something. It is too early to talk about it. It is with YRF," Ali said. The "Gunday" helmer is elated with the success of "Sultan".

"We did not anticipate this massive response to 'Sultan'. What has touched me is the repeat value for the film... Audience is watching the film again and again," he said.
