Mumbai, Oct 23 (IANS): Actor Hrithik Roshan, who is currently busy promoting "Krrish 3", says the team might come up with "Krrish 4".

"All the other franchise like Spiderman, Superman all those films were revamped in a span of three to four years. This is one film which has completed a decade, which is great, and maybe you will find a 'Krrish 4' in future. You never know," the 39-year-old told reporters during a group interview.

"Hopefully we will also make 'Krrish 4'," he added.

"Krrish 3" is the third film in the franchise that began with "Koi Mil Gaya" in 2003 followed by "Krrish" in 2006. Also starring Vivek Oberoi, Kangana Ranaut and Priyanka Chopra, the film is a sci-fi thriller that will take forward the story of a superhero, played by Hrithik.

The actor says a lot of new things have been introduced in "Krrish 3".

"We are for the first time introducing muteness in our cinema. It is exciting for me as there are lot of new things to look forward to. Progress has been tremendous from first 'Krrish'," he said.

Directed by Rakesh Roshan, the movie is slated to release in November.
