Filmmaker Ashutosh Gowariker, who is making Mohenjo-Daro with Hrithik Roshan, says he is happy that finally the film, on which he has been working the past two years, will go on the floors.“I have been working on the script for the past two years now. I am glad that finally it is happening," Gowariker said here Tuesday at the first look launch of the film Unforgettable.After helming successful historical drama Jodhaa Akbar in 2008, Gowariker came out with period drama Khelein Hum Jee Jaan Sey in 2010, but it was a flop.This is his second film with Hrithik after Jodhaa Akbar.“I will be starting it in three-four months time. I am looking forward to it. It's Hrithik and me again after a long time. I am very excited and looking forward to it," the Swades director said.
