Director R. Balakrishna of Cheeni Kum fame has once again teamed up with Amitabh Bachchan in Pa and says he is giving the legendary actor a complete makeover.

Big B is said to have agreed to cast off his beard for this emotional drama, although Balakrisha would not confirm the news.

"I'm not going to tell you whether I've asked Mr Bachchan to shave off his beard or not. But for sure, this is going to be his most startling makeover in recent times,” Balakrishna said.

After Sarkar and Sarkar Raj, Amitabh and son Abhishek Bachchan will again be seen playing father and son in a film.

"Pa will be a far more emotional story than Cheeni Kum, which was far more caustic, dry and sharp-tongued. Actually, Cheeni Kum was inspired by one scene in Raj Khosla's Dostana where Mr. Bachchan had confronted Zeenat Aman. The look of utter disdain and sarcasm in his eyes remained with me. That's how his character in Cheeni Kum was born.”

In Pa, Big B plays someone he has never played before.

"While in Cheeni Kum he was a character I had seen earlier, in Pa he's a totally different person. It's a very emotional father-son story, but the emotions won't be melodramatic.”
