Superstar Rajinikanth, who was out of action for nearly two months, will be back on the sets of upcoming Tamil sci-fi action drama 2.o later this month.

"Rajinikanth sir is fully fit and he plans to join the sets later this month. The producers had a courtesy meeting with him at his residence over the weekend. He had told them that he feels much better now and can join the team soon," a source close to the superstar said.

Rajinikanth was on a month-long US trip with his daughter Aishwarya, and returned to India on July 24.

As part of his vacation, the Enthiran actor is rumoured to have attended a detoxification programme. It is also reported that he underwent a surgery, but nothing is confirmed.

The superstar spent some time in Satchidananda Ashram in Virginia.

In filmmaker S. Shankar-directed 2.o, a sequel to 2010 blockbuster film Enthiran, he returns as scientist Vaseegaran.

2.o, which is being made on a budget of Rs.350 crore, also stars Bollywood actor Akshay Kumar as the antagonist, apart from Amy Jackson, Sudhanshu Pandey and Adil Hussain.
