Singha with the gang leaders and contestants at the shoot in Shillong

"I'm the boss here," Rannvijay Singha smiles, moments after chiding a crew member for causing disturbance while revving up a bike metres away from us in the midst of this interview. We tell him the fact is evident, for, only an hour ago, he took us off-guard by yelling at a crew member on being bothered by the disturbance in his earpiece while shooting for the Shillong leg of MTV Roadies Xtreme. The calm and composed host - or "ring-master" as he is now called - of the long-running stunt-based reality show isn't particularly known to lose his temper. "He needs a Xanax," someone whispers in our ear, but before we could nod in agreement, a voice louder than his retorts, "Okay, enough! Get on with the shoot." The agitated director, running against the clock, yells at the bevy of celebrated names - apart from Singha, also including Neha Dhupia and Nikhil Chinapa - filming for the task. Popular though they all are, they merely quiet down and get on with the work.
