"The only difference between the two is Kid Krrish is better than Krrish," Hrithik said.
Kid Krrish will be premiered on a children's channel on October 2 at 12 noon.
"Kid Krrish can jump and do everything without any help. The similarities, I feel, is we have the child alive inside us," added the actor, saying his two sons - Hrehaan and Hridhaan - have already seen Kid Krrish.
"Both my kids have seen the first movie of Kid Krrish and they have fallen in love with it. So it's already successful."
Filmmaker Rakesh Roshan's Filmkraft Productions partnered with Turner International India and Kerala-headquartered Toonz Animation to create four animated movies based on hit superhero movie Krrish.
The partnership was announced earlier this year and planned to bring India's favourite superhero Krrish in an animated form.
Rakesh Roshan said that for the first time a Bollywood character has got an animated version.
"The character of Krrish has been idolized by every child in India and has become an iconic superhero. We believe that Kid Krrish will be the new superhero for a whole new generation of children and a benchmark in animated series of live action films," he said.
Currently the Roshans are gearing up for the release of Krrish 3.
Slated to come out on November 4, this is the third film in the franchise that began with Koi Mil Gaya in 2003.
