"When your wife is on the sets with you...your behavior changes. There are lots of restrictions...there is always a discipline on the sets. Or else the situation at home becomes tense...out of control," Bachchan said to guffaws at a promotional event of the film on Friday evening.
In recent years, Mr and Mrs Big B have acted together in Karan Johar`s `Kabhi Alvida Naa Kehna`.
Directed by Abhishek Chaddha, `Ganga Devi` revolves around the theme of reservation for women in elected bodies.
Bachchan, who plays a key role, said Sawant was like a member of his family. "I am glad that I am a part of this film. Deepak is like a family. I know him for 30-35 years. He is my make-up man and he takes care of my face. It was my duty to give him something in return. When he approached me for this film, without any hesitation I did it."
Big B had appeared in Sawant`s previous Bhojpuri films including `Ganga` and `Gangotri`.
