/> Onir whose first two films My Brother Nikhil and Bas Ek Pal provided an interesting study in form content and style, is all set to start his third film in December.

Tentatively entitled Labyrinth the project will go into the sensitive and burning topic of human trafficking.

Onir is deeply immersed in the process of researching this deep-rooted malaise.

"I find it very tough to maintain a balance and not get carried away. I want to keep the subject sensitive and not bring in the sensational element at all. But the subject really moves me. I want to give topic a global spin.

For that, the United Nation will provide authenticated statistics and facts. I also want to bring in a German scriptwriter to fine-tune my script after I'm done with it."

Since this film will take Onir to various parts of the world, it'd be his most expensive film to date.

"There'll be multiple stories and an ensemble cast. I'm handling the theme very carefully. I want it to finally be a gripping and emotional story. But yes, the global nature of the theme requires a certain budget. I'll shoot in India, Nepal and the Middle East. So Labyrinth won't be an inexpensive film. There would be known faces in the plot.

In another two months Onir would put the final touches to his script, and then the casting begins.

"Going by the nature of the subject I need fresh faces. I'll be auditioning a lot of young boys and girls for roles. Of course there'll be some known actors too."

The film will be primarily in Hindi. "But it will have smatterings of English, Nepali and Arabic. And yes, it will have songs in the background. I love songs."
