SINGAPORE - The latest instalment of the hit Indian science-fiction film franchise Krrish opens across the world on Friday.
But Krrish 3, in which Bollywood superstar Hrithik Roshan plays the titular superhero, has already been buzzing on YouTube.
The actor, who is known for his slick dance moves, has had nearly four million views for a song from the movie, Raghupati Raghav. It is a classic Hrithik Roshan song-and-dance deal, complete with rippling biceps and nifty feet grooving to the peppy beat of the catchy number.
In fact, he is so in control of the moves that Bollywood's It-girl Priyanka Chopra, his co-star in the movie, hardly matters in the song.
But making Krrish 3, one of India's most successful superhero series of films, has been hard work for him for the better part of three years. Most of the time was devoted to the scripting, pre-production and planning of the film, which was directed by Roshan's father Rakesh.
Both father and son say they believe in "meticulous planning", so they do not lose a single day during their shoot.
Roshan senior conceptualised the lead character played by Hrithik as a "superhero with human powers". Krrish took off from his earlier film Koi... Mil Gaya (I Found Someone, 2003) - the first of the Krrish series - whose E.T.-like character called Jadoo turned out to be a huge hit among children.
Krrish (2006), which had a budget of $13.8 million, grossed more than US$18million at the box office while Koi... Mil Gaya was made on a budget of US$460,000 and grossed US$1.2 million.
When asked why the two earlier Krrish films have been so popular when other Indian science-fiction superhero films such as Ra.One (2011), starring Shah Rukh Khan, have had limited success, Rakesh Roshan says it was due to the franchise's slow build-up.
He adds that he had made "11/2 films to build the foundation" for Krrish 3, referring to Koi... Mil Gaya and Krrish.
This allowed him to fix all the kinks and make the special effects better.
