With Devara, koratala siva made a sort of return and the film grossed a lot of money at the box office. This movie basically revitalizes Koratala's fame, however ntr deserves most of the credit for pulling it off. Regarding the director's viewpoint, one may argue that even with Koratala's return, he could still have trouble landing a top-tier star for his next project.
The top five actors in Tollywood, ntr, Allu Arjun, Mahesh, Prabhas, and ram Charan, are all working on different projects. Mahesh is the only one not filming right now because he hasn't started work on Rajamouli's movie. Due to this, there have been rumors that koratala could be able to utilize Mahesh Babu's goodwill to secure him for a short film before he begins filming Rajamouli's picture.
Koratala and Mahesh previously completed bharat ane nenu quickly, and this was mentioned as a sign of things to come for their future partnership. However, it should be acknowledged that this is also out of reach. Notably, Mahesh has already begun growing out his long hair and beard in preparation for Rajamouli's movie. Mahesh's ability to sign a new movie and Rajamouli's approval are currently unattainable. Therefore, it is reasonable to conclude that there is now very little chance of Mahesh and koratala working together on a movie.
