After teaming up with Aamir Khan in the hit movie "Ghajini", Tamil director director Murugadoss now wants to work with Shah Rukh Khan and says he is working on a story right now."Yes, I'm working on a subject. I had a meeting with Shah Rukh Khan once and I discussed a story with him. But frankly nothing has been finalised. We are still to meet many a times before a decision is taken," Murugadoss told reporters Monday at the launch of new Kannada film "Suryakanthi".
