Actor Kunal Kemmu, who will soon be seen in zombie thriller "Go Goa Gone", says the film answers all the relevant questions related to zombies.

"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.

Co-produced by Saif Ali Khan, "Go Goa Gone" is about two friends, played by Kunal and Vir Das, who travel to Goa with another friend.

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.

Co-directed by Raj Nidimoru and Krishna D.K., "Go Goa Gone" also stars Anand Tiwari, Puja Gupta and Saif and is slated for a May 10 release.
