i don't know much abt his financial side, but I do know from certain sources that he has enormous reach in the film industry as well as music circles in Europe and even Australia!
IR going to Hungary for Hey Ram was at Kamal's behest - it was a collaborative thing but Kamal had prior knowledge abt such things as much as IR did!
thats just one sample/example - Kamal's reach stems from his painstaking research + curiosity + desire to constantly learn - adhellaam avar rangey vera - he is heads and shoulders above everyone else in these aspects.
thats why the VR release issue has left such a very bad taste - unforgivable treatment - antha avala nilai yaarukkumey yerpadakkoodaadhu - of all people it happened to Kamal!
