Maddy, it must be mentioned, is a national-level golf champ and winner of several national and international prizes for the game.
Mr Bachchan had never played golf before.
"Or so he said, " says the still-dazed-and-dazzled Maddy from Pune. "But seeing how he played I was shocked. No one except Mr Bachchan can be so good at a game he has never played before."
It happened suddenly when one day Mr Bachchan decided to join Maddy at the golf course. "I thought I'd be privileged enough to teach him a few moves. I was stunned at the way he played. He was spectacular.
And if this was his first time ever at golf then I've just become an even bigger of his, " says Maddy who played an Amitabh Bachchan fan in Ramji Londonwale and even got the mega-star to make an appearance at the end of the film.
Now Maddy is toying with the idea of a film based on the game of golf featuring Mr Bachchan and Maddy.
"I don't know how he did it! He's unbelievably athletic. His hand co-ordination is extraordinary. Other people generally take four years for what he did on the golf course on his first day...and so easily. He has phenomenal pick-up powers whether it's on the golf course or on the sets."
Not much of a card-player either the Big B picked up the cards game so fast for Teen Patti he left Maddy and other team members gasping. "He's extraordinary in whatever he does. I feel like his pupil, " says Maddy who plays a professor in Teen Patti.
"And then I go right back to playing the student in Raj Kumar Hirani's 3 Idiots. But being around the Big B I always feel like a student."
