Veteran actor Boman Irani says he took time with his maiden directorial venture as he was waiting for the right script, which he found in "The Mehta Boys", a film about evolving dynamics between a father-son duo. "At 35, I became a photographer; at 44, I became an actor; and at 65, I became a director and a writer," Irani said about the movie at the red carpet of the inaugural Indian Film Festival Germany. It is the opening film of the three-day film gala, which began on Friday.
