Who will direct Pawan for Dasari's production?

Pawan Kalyan has already announced that he has promised to do a movie for veteran director and producer Dasari Narayana Rao. As Dasari is going through some problems, Pawan Kalyan came forward to help him. 
 
Dasari who celebrates 72nd birthday on May 4th has also reiterated that he would be announcing the movie with Pawan Kalyan later this month. He informed the media that Trivikram has agreed to pen the script for this but he refused to reveal the director's name.
 
Speculations are rife about the director's name that include several top directors. 
 
Though Dasari suggested couple of names to Pawan Kalyan, the Powerstar is yet to confirm any one of them. Pawan recently launched a movie in the direction of S J Surya which is being produced by Sharat Marar.
