It was a Mega gaffe from Megastar Chiranjeevi.  Speaking at the pre-release event of 'Rangasthalam', the proud dad didn't realize he was revealing a suspenseful point while praising his son's performance.

"I was speechless on watching Charan's performance in the movie.  For example, in the scene where Aadhi Pinisetty dies, his performance is awesome," the 'Sye Raa' actor said.  

He actually repeated the words 'Aadhi death scene' one more time.  A minute or so later, Chiru realized that it was not a success meet but a pre-release event!  

Twitter reacted immediately after the gaffe.  "Aadhi death scene aaa.. ante aadhi sachipothadu.. megastar entha pani chesav.  Excitement story cheppestunav," said a user.  "Aadhi Chanipothadani Leak Chesaru.. Megastar #Rangasthalam But already telsu maaku.. Gunny bags scene in this movie too emotional," said another user.
