An excited Rishi took to Twitter on Thursday to thank Big B.
"Wonderful to work again with the legendary Amitabh Bachchan. Thank you Amitji, it never felt the 26 years old hiatus. We connected instantly!" Rishi tweeted.
The film that is said to be based on Saumya Joshi's Gujarati play "102 Not Out", will see Amitabh playing a 102-year-old man while Rishi will portray the character of his 75-year-old son.
