Not only for the top stars,even the top directors of the industry tend to line up their films with different heroes.
Trivikram used to be busy directing NTR, Bunny and Mahesh...but now his plight seems to be different.
His film with NTR got cancelled and the hero is not going to be available till 2023 as he has several lined up projects with Koratala Shiva, Prashant Neel after RRR.
Right now Trivikram is busy with Mahesh's film and thought of doing with Bunny after that. But Bunny has to complete Pushpa first. Then he has films with Boyapati and Venu Sriram. So, Bunny is not free for th next two years.
No top hero has dates now including Pawan Kalyan. So there is no other way for Trivikram than trying with Ram Charan. Otherwise, for a change he may direct a small film and fulfil his long standing pending dream.
