The makers of Suriya-starrer S3 aka Singam 3, which is inching closer to completion, are currently canning the climax action sequence in Talakona forest near Guntur district, Andhra Pradesh, a source said.

"The climax shoot started last week in Talakona forest. They’re filming a high-octane action sequence featuring Suriya and Anoop Thakur Singh," a source in the film’s unit said.

It’s because of the hectic climax schedule that Suriya couldn’t be present to welcome Indian captain Mahendra Singh Dhoni when he was in the city to promote MS Dhoni: The Untold Story.

Dhoni met Suriya’s kids and confessed he’s a great fan of their father.

S3, the third part in the "Singam" franchise, is slated for worldwide theatrical release on December 16.

Directed by Hari, the film also stars Shruti Haasan and Anushka Shetty. Anoop Thakur Singh is being introduced as the antagonist.
