Abhishek Bachchan, who plays the title role in the film, could not attend the press meet at PVR Plaza due to his father's illness.
Organised by PVR Cinemas, the conference was supposed to start at 2 p.m., but the stars arrived an hour late.
However, the director made it up by apologising for the delay.
Throwing light on his second film, Sippy said "Bluffmaster" is different - it has a love story, different kind of music, lots of style and attitude and above all a talented cast, including well-known actors Nana Patekar and Boman Irani.
The director and his team spoke highly of Nana and said it was a pleasure working with him.
Priyanka, looking resplendent, conveyed Abhishek's message to the press apologising for not being able to attend the meet.
Incidentally, the premiere of the film, which is to take place Dec 15 at Cinemax Infinity, Mumbai, has been cancelled due to Amitabh Bachchan's illness.
