"Nothing has been finalised yet. I have a few stories in mind, but I'm waiting to hear from him (Chiranjeevi). None of us know what is going to be his next film. I think it will make sense when he announces it," Vinayak said.
It's being reported that Chiranjeevi, who will turn 59 Aug 22, is expected to announce his 150th film, which will be a landmark moment for him as well as his fans.
Recently, Ram Charan came forward with an offer to pay Rs.1 crore for a suitable script for his father's next project. He is also expected to produce the film.
"Ram has taken special interest in his father's film. He wants it to be a special film that will be remembered for a long time," he added.
Vinayak is currently awaiting the release of Telugu romantic-actioner "Alludu Seenu", featuring newcomer Bellamkonda Sai Srinivas and Samantha Ruth Prabhu.
He says it was his 'dharma' to launch Srinivas.
"Had it not been for Srinivas's father Suresh, I would've never become a filmmaker. He produced my first film and I always was indebted to him. When he asked me if I could launch his son, I thought it was my dharma," he said.
"Alludu Seenu" produced by Bellamkonda Suresh is slated for release July 25.
