It has been officially confirmed that Arjun is going to work with Tamil Director Atlee for his upcoming project, which is going to be produced on a huge scale. This project was officially announced already, and it is preparing for the start of the shoot soon.
The fact here is that Allu Arjun has prioritised this Tamil Director over the conventional option of Trivikram Srinivas, who had been waiting for a long time to work with him.
After answering that Arjun has his interests elsewhere, Trivikram has decided to overseas his own options, and this could possibly be the reason why he is in talks with Venkatesh now.
Apparently, the collaboration of Trivikram and Venkatesh could be happening very soon. This is the alternative plan that Trivikram had to come up with in the last minute due to the choice made by Allu Arjun.
