When Dadu Dharmendra surprised Father-Son duo Sunny- Karan

Last Friday, when Sunny Deol was shooting son, Karan's debut film, Pal Pal Dil Ke Paas, at the Buddh racing circuit in NCR, he had a surprise visitor!

Dharmendra was in Delhi for some work and had heard that they were shooting some racing car sequence. So he decided to drop by and watch his grandson in action. He didn't want to disturb them at work, and hence didnt inform anyone about his arrival on the set.   

When Dharmendra reached the set, the atmosphere had shift in mood. On seeing his father, Sunny had a hint of tears in his eyes. Even though Sunny didn't say anything, Dharmendra noticed this. Sunny said that his father's visit to the set seemed unreal and unexpected.
