The entire Charles Sobhraj project, that has been in the pipeline of director Prawaal Raman for the last three years, has gone in for a scriptural revamp. Prawaal, whose last film 404 was a chilling horror film, has done away with the lengthy bio-pic and written the script to suit Saif Ali Khan who plays the character. Earlier, the plan was to cast Sanjay Dutt and make it an authentic bio-pic. But, then litigations loomed large over the project.
