"We know there are a lot of people in our country who haven't seen such (zombie) films. What are zombies? How do they become a zombie? And what should be done with them? Answers to all these questions are being given in the film," the 29-year-old said here in an interview.
"The story has been told in a simple manner... So if you haven't seen a zombie film before, or you don't know what a zombie is, you can still watch it. Even our characters in the film don't know what are zombies and what is happening with them," he added.
Vir said physically it was a demanding project.
"This was not a studio film, no air conditioners and all," he said and added that most of the film was shot in the sea and the forest.
"Everyday we would run in the forest, lie in a boat in the sea in intense heat. It was a physically very tough film," Vir said.
