Shankar's magnum opus 2.0 is about to hit theatres and the usual hype and frenzy surrounding a Rajnikanth release is tangible. The director during a recent press conference spoke about the challenges he faced during the filming and reasons for the film's delay and budget overruns. The VFX company that was tasked with the mammoth visual effects of the film had failed to deliver in time and kept seeking extension over and over again. The initial target to deliver 2 months prior to the film's initial release was pushed to six months and subsequently to a year. Shankar realizing that the small time company was unable to handle the VFX work of such a grand scale decided to hire another agency for the job. The end product was much to the director's liking. Shooting the entire film is 3D was a huge challenge as well. The 3D camera was limited to just 4 lenses and the camera rig could not be moved easily with the setting up taking atleast half an hour. Even a single cable getting disconnected took a lot of time to rectify leading to each shot requiring a lot of work and toil.
Shankar heaped a lot of praise on the film's music composer AR Rahman saying that the music was on par with Hollywood Batman and Superman flicks. He also praised Akshay Kumar for his patience with the complicated makeup and prosthetics required for his character. Although the villain, his character has been given multiple shades and would a pillar for the film along with superstar Rajnikanth.
