Speaking at the audio launch of Tamil actioner "Lingaa", Rajinikanth told reporters: "Everybody wants me to join politics. I'm aware of its depth and danger. I'm not afraid, but just a little hesitant. It's not in my hands. If god is willing, I will serve people."
"I think doing films with a social message is also some kind of service to society. Making films and entering politics is easy, but emerging victorious is tough in both," he added.
The superstar wanted director K.S. Ravi Kumar to complete "Lingaa" in six months.
"The only person capable of finishing the film in less than six months was Ravi Kumar. I'm happy he did it," he said.
He also added that Ravi Kumar looked after him like a child. He was touched by the love of the film's crew.
"Lingaa", slated for a Dec 12 release, comes after the failure of Rajinikanth's "Kochadaiyaan", an animated film directed by his daughter Soundarya.
"We lost some money through 'Kochadaiiyaan', but I learnt a lot from the experience," said Rajinikanth, who wasn't sure if he could ever act after his recent illness.
In 2011, the 63-year-old actor was hospitalised after he suffered respiratory problems on the first day of Tamil film "Rana", which was subsequently shelved.
"I never thought I could return to acting after my illness. I think I need to thank my fans for giving me the energy to continue acting," he added.
