“I’ve been emulating superheroes all my life; a recurring childhood dream was to fly. After doing that in my dreams for all these years, it’s suddenly coming true in real life,” says Hrithik Roshan, who is back to playing the masked crusader in ‘Krrish 3’, the 3D science-fiction sequel to ‘Krrish’ (2006). While the 38-year-old actor is jumping off skyscrapers, his six-year-old son, Hrehaan, wants to hop off stools. According to the star father, he has just about begun understanding the art of slow-motion fighting. “I had to sit him down and explain the laws of gravity,” he laughs. Last year, Hrithik’s father, producer-director Rakesh Roshan, almost considered scrapping the sequel after watching his son writhe in pain from a knee injury and a double slip disc. “I was in a dark place that was full of negative vibes,” reminisced Hrithik, who consulted friends, therapists, surfed the Internet and finally connected with trainer Kris Genthin and his nutritionist wife Marcia Johnson to get back into shape.
