With its trailer release on Wednesday, Ayan Mukerji's 'Brahmastra' has become the most talked about film of Bollywood at the moment. It is widely known that 'Brahmastra' was in production for around five years while Ayan himself has been working on it for around 9 years. So naturally, the filmmaker is often questioned about why the movie took so long and how did he manage to stay motivated throughout the whole process.

In a recent interview, Ayan credited megastar Amitabh Bachchan for keeping him motivated. According to a report in ETimes, he stated, "People ask me how I’ve dedicated 9 years to making Brahmastra and I tell them look at Bachchan sir, he has literally dedicated his entire life to the craft of acting and filmmaking. When he’s not on set acting, he’s writing about cinema, he’s creating music, he’s reading, he’s planning the next big project and he’s been doing all of this for more than 5 decades. His commitment to the craft is simply inspiring."

He further added, "One of the most inspiring aspects of Bachchan sir’s work ethic is his commitment. We were shooting a lot with the blue screen and getting cues from your co-stars is very important in such a setup for any actor in front of the camera. Despite having finished all his shots, Mr Bachchan would always be the first one to take his position on the marker and give every single cue to his co-stars. He would not retire to his van or his room, he would always hang around the camera and be there to give every cue. Watching him be so meticulous, even at his age, was a real inspiration for all of us.”
