The film was scheduled to shoot in November, but will now start at least a month later to accommodate Bachchan, whose wife Aishwarya Rai Bachchan is expected to deliver their first child in November.
An IANS source said: "Yash Raj had Abhishek's dates from November onwards. But Aishwarya is due in November and Abhishek wants to spend some quality time with his baby and wife before getting back to work. Hence, he requested YRF to postpone the shoot for a month or two.
"Bachchans are family to Yash Chopra. He immediately agreed to give Abhishek some time off. He asked the makers of Dhoom 3 to begin shooting the film only after Abhishek is ready.
"Abhishek in turn has agreed to start shooting mid-December. Now depending on the availability of the locations and technicians, Dhoom 3 will go on floors in December this year or January next year."
However, a Yash Raj Films spokesperson added: "Well, our schedule of Dhoom 3 has still not been finalised. So, it's a little premature to be discussing a postponement. And yes, most certainly we will keep in mind the arrival of joy in the Bachchan household while planning Abhishek's schedule."
Dhoom 3 is expected to start production in December or January 2012.
