Rahul Mittra, Sanjay Dutt's friend and producer of his upcoming film 'Torbaaz', has denied the rumours that the 61-year-old actor, who has been diagnosed with lung cancer, is terminally ill. "This is utter rubbish," he said. "Sanju is undergoing preliminary treatment in Mumbai and results of certain tests have yet to come...Please stop speculating," Rahul added.
