Simbu is busy with Vallavan as he is donning the twin responsibilities of acting and direction. For shooting a college sequence, a huge set has been got up at Vijaya Vauhini Studios. Several scenes featuring Simbu, Nayantara, Sandhya and Reema Sen besides several junior artistes were shot here. Meanwhile, all the heartburn between Simbu and producer Thanu has been sorted out. Thanu has reportedly agreed to pay Simbu the extra amount he demanded. Simbu has therefore started dubbing for Thotti Jaya. The extra amount we are told is around Rs. 25 lakhs.
