Well, there are about several theories, speculation, rumors and reports
regarding this concern. Some sources say that Emraan was approached with
role in M3, but he refused it because Bhatt didn’t comply with his
suggested edits in the plot of the movie. On the other hand, Mahesh
Bhatt claims that Vishesh came up with dropping Emraan from M3 and
replacing him with Randeep, while giving opportunities to other
newcomers, including Mona Lizza and Aditi Rao Hydari.
