He says that the film has not only strengthened their bonding, Varun also saved his life during the Bangkok shoot.
"Directing Varun has brought us closer together. During a schedule in Bangkok when I took ill, I could feel Varun's panic," said the director informing that it was a reaction to medicines that almost killed him in Bangkok.
"I had taken a fall in Bangkok and was taking medicine for the injuries. I made the mistake of gulping down the medicines on an empty stomach. The medicines reacted and I passed out. My son saved my life that day."
"Main Tera Hero" will see Varun romancing Nargis Fakhri and Ileana D'Cruz when it comes out April 4.
