Ajay Devgan and Aishwarya Rai will begin shooting in August for Rajkumar Santoshi's biopic on Prithviraj Chauhan.

Initially, there had been speculations about Ajay reconsidering his decision to act in the project after he heard that Sunny Deol was also planning a film on the same subject.

But Ajay's business manager, Kumar Mangat, reveals there is no question of backtracking now.

"Rajkumar Santoshi has been working for three years on the subject and the role is something Ajay has cherished. Ajay is determined to make a success of his role in the film," Mangat maintained.

The film will now be shot on a six-month start-to-finish schedule in Jaipur and Jodhpur.

Despite many of his past few releases failing to get encouraging responses at the box-office, Ajay has a lot of hopes pinned on his forthcoming line up. There's Harry Baweja's "Main Aisa Hi Hoon" to start with, followed by Neha Arts' "Tango Charlie", Karan Johar's "Kaal" and Prakash Jha's "Apaharan".
