Comedy King David Dhawan surprised his assistant Umesh by visiting him on sets of his debut film, 'Kya Kool Hain Hum 3' and also shot few scenes for his film.

Debutant filmmaker Umesh Ghadge was in for a huge surprise recently while he was shooting his debut film, 'Kya Kool Hain Hum 3' in Mumbai. Not many know that Umesh has assisted the veteran filmmaker David Dhawan on several films such as Partner, Chashme Baddoor and Main Tera Hero among others.

Much to Umesh`s surprise, David dropped by his film set in Andheri recently. A source present on sets informs, "David saw the footage of what was shot on that particular day and got quite involved in the process that he ended up shooting two scenes."

Tusshar Kapoor, who had also assisted David in the past, was very excited to have the filmmaker on sets. Besides Tusshar, 'Kya Kool Hain Hum 3' stars Aftab Shivdasani and debutant Mandana Karimi.
