According to a report published in Indiaglitz.com, Mohanlal and Abu Salim visited the shooting location of Baahubali. Later, people started speculating that they were going have cameo roles in the sequel. A few online entertainment portals also started circulating the rumours.
However, there is no official confirmation from the filmmakers or Mohanlal and Abu Salim. So, to know the truth we have just to wait till the movie is out.
Baahubali: The Conclusion, which is slated for an April 2017 release, is expected to break records at the box office, just like the first part.
