Abhishek and Aishwarya Rai [Images] Bachchan's new film with Mani Ratnam -- tentatively called Ravan -- will be shot in a forest near the Athirapally waterfalls in Kerala [Images]. The film's shooting with other artistes has already started; the couple will join them very shortly.

According to a source, Mani Ratnam is finalising the locations, and the shoot will start sometime next week. Incidentally, the Athirapally waterfalls is Mani's favourite location. He had earlier filmed parts of the Dil Se song, Jiya Jale (picturised on Preity Zinta [Images]), and the Guru song, Barso re (picturised on Ash) at the same location.

Mani Ratnam was earlier toying with the idea of shooting the film in Sri Lanka [Images]. But he abandoned the plan after insurgency by Tamil rebel group LTTE [Images] peaked against the Sri Lankan government.

"It was not considered as a safe haven for shooting, so the shooting of Ravan shifted to Kerala," said a source.
