The affair, hyped by Indian media as "the wedding of the century," was filled with the melodrama so beloved in Bollywood, India's flamboyant Hindi film industry: secrecy, dance routines and even a suicidal fan who claimed to be the groom's jilted lover.
Bachchan bobbed his head and punched the air with his hands in time to a Bollywood tune played by an accompanying band of red-turbaned musicians.
He then made his way to a huge, flower-filled, air-conditioned tent encircled by gold curtains in the garden adjoining the Bachchan family home — where — to the sound of trumpets, drums and clanging cymbals — he and Rai reportedly exchanged garlands and wedding vows.
Rai remained hidden inside the barricaded venue, but the Indian media was split down the middle with reports that she either wore a red-and-gold, intricately embroidered sari, or a gold-and-cream creation.
Bachchan, 31, and Rai, 33, were engaged in a private ceremony in January. They have appeared together in several films.
Rai, who first captured India's attention when she was crowned Miss World in 1994, has become one of its biggest stars and one of India's most recognized faces overseas. She has acted in more than 30 movies and starred in several commercials for cosmetic and cola companies.
Hundreds of fans lined the roads, climbed trees or scaled buildings, hoping to catch a glimpse of the wedding party.
However, the festivities were marred when a young woman slit her wrists outside the Bachchan home in Mumbai early Friday.
Identifying herself as Jhanvi Kapoor, she said Bachchan had promised to marry her after they met when she was one of the dancers in a promotional music video for a movie "Dus" ("Ten"), in which Bachchan starred two years ago.
She was taken to a nearby hospital for treatment, then arrested by police for attempting to commit suicide — a crime in India. She was later released on bail of $238.
"This is a stunt," said police officer A. Mohite. "She seemed to have done this purely to catch the attention of the media."
