Though underway in full earnest in Peru with the shooting of a song, there seem to be things about Endhiran that are still troubling Shankar's mind. It is no secret that Endhiran, then Robot, was affected by the demise of writer Sujatha. He had been a trusted associate and screen writer for Shankar. We had reported that Shankar had called upon writer Balakumaran to fill the void. Balakumaran had earlier worked with Shankar in Gentleman, Kadhalan and Jeans.

But even after the completion of scripting works, Shankar seems to see room for improvement, trademarks of a perfectionist. With the sci-fi specialist Sujatha no longer around to give the much needed advice, Shankar has chosen to look beyond Kollywood, beyond Bollywood and into Hollywood. Shankar seems to have set sight on Manoj Night Shyamalan, known for making films like Sixth Sense, The Village, Unbreakable, Signs and The Happening. Shyamalan may not be a complete sci-fi specialist but he knows how to keep people on their toes and that's exactly what Shankar wants. The top Kollywood director is said to have approached Shyamalan for discussing the finer elements of the script of Endhiran.
