Vicky Kaushal has shared throwback pictures from the sets of 2012 film 'Gangs of Wasseypur' in which he worked as an assistant director. "The first clap was nerve-wracking," he wrote. "After many rehearsals...I did give my first clap, 'Scene 72A, shot 1, take 1', the first thing I said in front of...camera and that's how it all started," Vicky added.
