Both these films are at the stage of their pre-production work. The work which is being carried out for both these projects have been huge. Since pre production is happening at same time there is a lot of overlap in teams.
So Ritesh decided to space it out for teams to be able to work smoothly. So much so that one whole floor has been assigned to each of the films. There are auditions which are happening with full swing for both projects simultaneously. Auditions which happen daily is an entire day process.
Hence Ritesh has dedicated one whole floor each for both films so that there is work happening precisely without any kind of stress.
