Amitabh Bachchan is making every effort to salvage son Abhishek`s career. Recently when the Big B saw Shararat at a special preview, he was so unhappy with Abhishek`s dialogue delivery that he`s asked his son to re-dub.

Shararat also stars Hrishita Bhatt, Amrish Puri, among others.With none of his films doing well at the box-office, the junior Bachchan desperately needs a hit.
