Vishal Tyagi, the special effects (SFX) supervisor of 'Dhurandhar: The Revenge', revealed there was no CGI involved in the making of the massive tanker explosion in climax. Tyagi said director Aditya Dhar was clear about not using CGI. "Imagine burning 500 litres of petrol for real...I was majorly concerned for Ranveer Singh, but he wasn’t as concerned himself," he added.
