It is for the first time that Kashyap and Big B will be working together in a full-fledged project, after shooting a scene for "Bombay Talkies (2013)".
"He is very demanding in a good way and especially when he decided that he wants to break new grounds and do something new. He is extremely demanding and has a lot of questions," Kashyap told reporters here at the launch of the show Wednesday.
The director of films like "Dev D" said that one should be prepared with their research and home work before working with Big B.
The yet-to-be-titled show will go on floor next week and is co-produced by Bachchan's Saraswati Creations and Endemol. It will be aired on Sony.
