Actor Manav Kaul of "Kai Po Che" fame was amazed at the dedication and perfection of megastar Amitabh Bachchan in their upcoming film "Wazir".

Manav is best remembered for his performance as the cunning Bittu in Abhishek Kapoor's "Kai Po Che" and Vishnu sir in Hansal Mehta's "Citylights", where he played a small-town man corrupted by a ruthless city.

He again plays a grey character in Vidhu Vinod Chopra's home production "Wazir".

"After working in the industry for a very long time, he (Amitabh Bachchan) still rehearses, he believes in being perfect. He doesn't waste anyone's time. His dedication even today towards his work is inspiring," Manav told PTI.

Besides Bachchan, the film stars Farhan as an ATS officer in the action thriller "Wazir".

"Farhan is an honest actor, he is a down-to-earth person. It's an absolute delight to work with him. Most of my scenes are with Farhan. He doesn't interfere with anyone's work, he is director's actor," Manav said.

"It's comfortable working with him. I enjoyed doing action scenes with him. He often gave me suggestions and we worked comfortably," he said.

The Bejoy Nambiar-directed film "Wazir" will hit cinema houses on January 8.

Manav will be seen next in Prakash Jha's "Jai Gangaajal" alongside Priyanka Chopra. The film is set to release in March next year.
