Ajay Devgn's highest budgeted film to this date.
Ajay Devgn suffered hypothermia whilst shooting a scene. It was a helicopter shot with the fan blades kicking up snow on his body & he was wearing only a leather jacket and jeans.
First Global Indian Film to have 3 trailers releasing simultaneously on August 8, 9 and 10th 2016.
Ajay Devgan had almost shelved the film as it had gone over budget with Rs 8-9 Crores having already been spent on extensive research and Pre production costs.
Ajay Devgan had gone to Canada to shoot the film but returned back without shooting a single day as he did not find the required snow to shoot the film.
