Akshay Kumar has played reel-life son of Amitabh Bachchan in lots of movies. In this relation Akshay and Abhishek seems brothers. "I've worked with Abhishek once. He has taken everybody by surprise. I knew this would happen. He was the dark horse once, but he has done enough to make critics ear their words. Abhishek's brilliant actor. The kind of maturity I got after 9 years, he got within one year and he just gets better with every movie. He's a great guy," says Akshay.
