In this blast from the past video, Varun Dhawan is seen scaring Shah Rukh Khan and Rohit Shetty on sets of 'Dilwale'

A lot of hard work goes into making a film but at the same time it's fun shooting for it. And when you have the likes of Shah Rukh Khan and Varun Dhawan together, one can expect a blast, sometimes in literal sense too, on set.

While the senior actors are often heard of pulling newbies' legs, this time Varun took the initiative to shock and scare none other than Shah Rukh Khan and their film's director Rohit Shetty.
