Filmmaker R Balki has revealed his upcoming movie, which has Arjun Kapoor and Kareena Kapoor Khan in the lead, will have a 'very special appearance' by megastar Amitabh Bachchan.

The yet untitled film will see Arjun teaming up with the 'Bajrangi Bhaijaan' actress for the first time.

"I will start shooting my next with Kareena and Arjun soon. It has Mr Bachchan in it. He is doing a very special appearance in the film. Without his appearance the film will not be possible," Balki told PTI.

The director, who is an ardent Bachchan fan, has worked with the actor in all the films including "Cheeni Kum", "Paa" and his latest "Shamitabh", which failed to create a buzz at the box-office.
