Praising the debutant, Sharman says Haider has made a beautiful film.
"While shooting the film, he (Haider) was directing it like a veteran who would have already shot 10 films. I even asked him how you are able to direct the film with such ease? He said, 'I was writing the film for two years and during that period, I also visualised it'," Sharman said in an interview.
"So, I think in those two years his hard work on the film would have been equal to that of 10 years and that's why he has been able to make such a beautiful film," he added.
"War Chhod Na Yaar", India's first war comedy, also features actors Jaaved Jaaferi and Ali Khan">Soha Ali Khan. While Soha plays a war reporter, Jaaved will be seen as a Captain in the Pakistani Army.
Jaaved feels an actor needs to respect a director irrespective of his experience.
"As an actor you have to understand that the person who comes to you, whether a newcomer or a veteran, you have to respect him as he is your director, your captain and he will mould you. He has written the story, he has a vision, he knows all his characters and identifies them and he knows how to mould the characters," Jaaved said.
"As an actor I can contribute to a level, like - we can do this, we can have this accent or I can keep my moustaches this way..," he added.
He added that due to a good interaction with the director, his character has come out very well.
