Wanted and Singham's arch-villain Prakash Raj has walked out of the Sanjay Dutt-Vivek Oberoi starrer Sher.

Known to be a radical professional and absolutely hassle-free at the sets, it came as surprise when one of the most film's actors accidently let loose that Prakash Raj has walked out from the site in Rajasthan.

Says a source, "I DO NOT know what really happened. Prakash Raj was alleged to play the villain. But now I'M shooting with Paresh Rawal instead. We heard Prakashji had some monetary issues." Further probing revealed not all was well in paradise. And it was not so simple as a dispute over the remuneration.

A source from Rajasthan informs, "Basically Prakash Raj walked out as a result of constant changes within the script. By the point he came to visit to truly shooting, his role was very different from what he have been narrated. Prakash who's used to playing pivotal parts in both Bollywood and South Indian cinema opted out due to the fluid script."

Surprisingly, Paresh Rawal who's known to be extremely fastidious concerning the script has stepped in as a last-minute replacement.

When asked about replacing Prakash Raj, Paresh honestly admitted to the re-shuffle. But Paresh added, "Initially I USED TO BE to play the role. But there have been date issues, and that i needed to opt out. Now they have been sorted. So I'M in."

Prakash Raj evaded comment.
