"Dharmaniki dhairyam thodaina vela," wrote Koratala Siva, unveiling the combo look of the Chiranjeevi-Ram Charan duo from 'Acharya'. It's Mega Power Star's birthday today and the poster makes it clear that the father-son duo will be seen as comrades-in-chiefs in the May 13th release.

Quote-tweeting Megastar's tweet, the 'Rangasthalam' actor wrote, "Acting alongside you is more than just a dream come true Nanna! Thank you. Can’t ask for a better birthday gift! You are my #Acharya (sic)."

The film, starring Kajal Aggarwal as Chiru's pair and Pooja Hegde as Cherry's pair, is currently in the final stages of being wrapped up. There were postponement rumours recently but the makers were quick to condemn them.

With music by Mani Sharma and cinematography by Thirru, 'Acharya' also has production design by Suresh Selvarajan. Editing is by Navin Nooli, who recently won a National Award for 'Jersey'.

Set in Dharmasthali, the film is expected to do a massive pre-release business.
