"As and when she wants to come back, is completely her decision... as and when she decides, when she sees a script she is inspired by - the decision is entirely hers. Currently she is very happy doing what she is doing," the 36-year-old said here at the launch of Sorabh Pant's book "The Wednesday Soul".
While most filmmakers may opt for novels to base their films on, Abhishek favours plays penned by young writers.
"I like to read biographies and autobiographies. But there are some wonderful plays out there that a lot of young, Indian talent is writing. I would love to do one of them," said Abhishek.
"I can't decide which one. Like I said, there is a lot of interesting material being written in India, I would love to delve into that resource to come up with a film," he added.
The Bachchan family is yet to announce the name of Beti B.
Abhishek is currently busy working on "Bol Bachchan" and "Chakravyuha". His two sequels - "Dostana 2" and "Dhoom 3" will go on floors soon.
