Sridevi -- one of the biggest names in Hindi cinema – died Saturday night in Dubai. She had been in the United Arab Emirates to attend the wedding of her nephew, Mohit Marwah.

Her body was due to be flown back to Mumbai on Monday on a charter flight.

Crowds have gathered outside Sridevi�s home in Mumbai to pay their last respects ahead of a cremation.

Sridevi, who was at her peak in the 1980s and �90s, was seen as the first female superstar in India�s male-dominated film industry. She was known for her impeccable comic timing as well as her dancing skills — a serious asset in country where song-and-dance melodramas are a movie staple.

Born Shree Amma Yanger Ayappan in the southern state of Tamil Nadu, Sridevi appeared in around 300 films and was awarded the Padma Shri, India�s fourth highest civilian award, for her service to the film industry.

Her acting career began at the age of four and by 13 she was cast in the adult role of a woman avenging her lover�s death.

She was considered one of the very few Indian female superstars capable of huge box-office success without the support of a male hero.
