Hrithik's 'boy in a man's body' role is rumoured to be inspired from Tom Hanks character in Robert Zemeckis's Forrest Gump. Hrithik doesn't see any resemblance, though, "I have not imitated him. I have just done my job."

According to Hrithik, the best part of making Koi... Mil Gaya was, "I could live my childhood [again]. I could eat as many chocolates as I wanted. I became a baby and everybody was so caring towards me."

From Kaho Naa… Pyaar Hai to Koi... Mil Gaya, Hrithik has seen a lot of ups and downs. The only difference, he points out, is, "I had to work harder for this film. It is a completely different subject."
