Amitabh is shooting for Prakash Jha's "Aarakshan" in Bhopal which is also his actress-wife Jaya's home town.
"As I work in Bhopal, my sasural, my wife's home, her mother who lives by herself there, shall dutifully prepare my dinner each night and personally come over to the hotel with it and sit beside me to feed me and supervise the meal.
Coercing me to eat more, to try this and that and whether it was appealing or not," Amitabh posted on his blog.
The film also stars Saif Ali Khan, Deepika Padukone, Prateik Babbar and Manoj Bajpai.
