Mumbai, March 24 : Veteran actor and director Rakesh Roshan reveals how his son and Bollywood star Hrithik Roshan entered the entertainment industry and decided to work with his father for understanding the craft and knowing the struggle of an actor to establish himself. He said: "When Hrithik was in college, he had two options: either he pursues further studies overseas or he assists me in making movies. The decision was left entirely up to him, and he ultimately chose to work as my assistant in movies."

There will be a day where you will act and sing as well!" 'Indian Idol 13' airs on Sony Entertainment Television. /IANS
