There were rumours that not satisfied with the original script (by SRK himself, Anubhav and Mushtaq) Shah Rukh Khan had handed over the entire work to David, to get that Hollywoodish touch to the superhero flick.
However, that is not the case. What is true is that David Benullo did visit the various sites (in Mumbai) which would be part of the backdrop of RA.ONE to visualize it. Actually, Benullo is writing the superhero part of the collaborative script by SRK, Sinha and Sheikh and they are working as a team.
The much awaited RA.ONE is expected to release sometimes during the first quarter of 2011.
