Krrish, Bollywood's version of Superman, has thrown a box-office challenge to the American counterpart.
Trade analysts estimate that the film earned an Indian record of $15 million in its opening week.
Almost one-third of the takings for Krrish came from overseas, mostly the United Kingdom and the United States.
"These are historic opening collections for a Bollywood film. India's first superhero is a super-hit," said Taran Adarsh, a leading trade analyst.
"This is just the first week. Many cinemas are sold out for days. And the way things are going, the movie could earn more than what Superman did."
Krrish, which cost $10 million, was considered an expensive production in the Indian film industry.
The story of a man with special powers who romances his lady love in between saving the world from a mad scientist has hit a chord with children, who love his ability to leap tall buildings at a bound in a black leather ensemble and a Batman-like mask.
"And something which is a hit with children will ensure their parents come along," Adarsh said.
Industry officials say the film is a huge success because the hero can tackle villains and save the world while singing and dancing - a feature of Indian films.
"The film is a workable mixture of what the Indian audiences adore - fantasy, adventure, romance and family values," said film critic Deepa Gehlot.
"The total package is a novelty for them."
The film is a sequel to the 2003 blockbuster Koi...Mil Gaya, considered to be Hindi cinema's first major sci-fi movie.
