Megastar Amitabh Bachchan, who has essayed complex roles effortlessly in his over four-decade career, says he has always found it tough to work with actor-director Farhan Akhtar.
While Farhan had directed Amitabh in "Lakshya", he co-stars with the thespian in the forthcoming film "Wazir".
Asked about the experience of working with Farhan, who is over 30 years younger to him, Big B said: "It was tough for me to work under Farhan and it was tough for me to work with him as an actor. Farhan has grown up in front of me. It was just wonderful to be in his company."
The 73-year-old said Farhan also expressed his views as a director for "Wazir", which is directed by Bejoy Nambiar.
"He was a director there ('Lakshya') and an actor here ('Wazir'). But during the making of this film, there are points that he may have viewed as a director and brought it up... that's very interesting," Big B said.
