Buchi Babu Sana has scored a blockbuster with his very first film, 'Uppena'. Sukumar, who is his guru, has penned a letter lauding him on the phenomenal success.
In the letter, the 'Rangasthalam' director wonders what Sana had learned from him to make a "great" film like 'Uppena'. "Unless I become my own student, I won't be able to fathom it. I am appreciating Sana for making me inquisitive about my own self," the letter adds.
The same is going viral on social media.
