However, the strange thing about these films is that once Thaman’s name got changed to SS Thaman, 15 consecutive films of his got flopped at the box office.
This was when he decided to change his name on screen and enforced the new tag of Thaman S. It turned out to be that this was the official name that was used for all of his films later.
Thaman then gave a big update on the upcoming film of Pawan Kalyan, which happens to be the most expected film from him in recent times, OG. This film is currently in the production stage now, and it is going to start with the shooting process again very soon.
Thaman revealed that Tamil superstar Simbu sang a song in this film, and it is other than the hungry cheetah song. This song has been recorded and loaded, and it will be released officially on the public forum on the very day that the shooting will resume.
