Filmmaker Nikhil Advani says he is "comfortable" working with a veteran like Rishi Kapoor, but admits the actor is a "tough taskmaster" to handle.

Rishi, 60, has an important role in Advani's new crime thriller "D-Day".

"Rishiji is a tough task master to handle, but I share a very good rapport with him as I have worked with him in 'Patiala House' (as well). We are very comfortable working with each other. It must be difficult for other directors, but not for me," said Advani.

The movie, releasing July 19, also features Arjun Rampal, Irrfan and Huma Qureshi.
