A source says, "Mr Bachchan was supposed to be seated in the front row next to Mukesh and Nita Ambani. But, he did not turn up and we heard he was at another event.
However, Abhishek Bachchan made up for his absence; he was given the seat that was reserved for Mr Bachchan."
Sources close to the star clarify that though he was approached, he had not confirmed his participation for the event. "He had committed himself to a brand launch on the same day," adds a source.
Anupama Chopra, festival director, says Sr Bachchan had been "extremely supportive" of the film gala and adds, "He could not attend the opening ceremony as he had a tight schedule. But, he has always been supportive and encouraging about the festival."
