Shekhar, who is teaming up with Rohit after seven years, said Rohit is one of the nicest persons and they wanted to work with him after "Golmaal" but somehow it could not happen because other projects kept them engaged all this while.
"Rohit is a hit filmmaker. He is very intelligent man and a fun loving person but very humble and down to earth, it is always a pleasure working with him," Shekhar told PTI.
The music composer duo have infused regional music with the contemporary elements to suit the script.
"Regional music was the requirement of the film and what we (Vishal and I) have done is we mixed it with our style to give it a sound which is organic and also imparts authentic southern-Indian feel," he said.

The composers have also roped in legendary singer SP Balasubrahmanyam for title song of the film. With the number, Balasubrahmanyam will make his comeback to Hindi cinema after 15 years.
"He is 67 years old but seems 20 with the kind of energy he has. He still sounds the same as he would 15 years ago, his voice has not changed at all. It took him just an hour to do the whole song! He is a fantastic human being and it's a matter of pride to have worked with a legend like him," said Shekhar.
Shekhar is currently judging 'Indian Idol Junior' with Vishal and Shreya Ghoshal. He is amazed to see the young talents in the show.
