Actor Hrithik Roshan in an interview to Zoom said that his father Rakesh Roshan was told that his 2003 film 'Koi... Mil Gaya' will end his son's career. "His well-wishers told him that your son is an action hero and you're making him play a mentally-challenged child in the film," said Hrithik. "Well, that got proved completely wrong," Hrithik added.
