In reality, these revolutionary groups struggle for the sovereign Assam by the means of an armed struggle and are declared terrorist by the government of India. One such group in Assam went on to the extent of exploding bombs in the vicinity of the film sets to stop the film shoot.
"It is not very clear that the blast was to threaten us, but as the subject of the film revolves around such separatist group and explosion took place nearby it was speculated by the officials as the warnings by such groups. Unit was given a protection by the local force and was asked to be alert all the time," informs the source from the scene of incident.
Though the fear prevailed, they continued to shoot until the completion of the film, and the unit is now back home safely. People who act in spite of their fear are truly brave!
