They lacked great acting skills or opportunity, but they did not succeed after one movie.
Bollywood is an extremely difficult place for an actor or an actress to succeed. Not only are there many competitors, the senior actors are so involved in movies that newcomers barely get a chance. Some people, however, make it through the competition to give one successful movie but the disappear after that. Here's a list of 5 Indian actresses who were one-time wonders and could produce only one hit movie in their career.
1) Diana Penty
She was one gorgeous actress who also won the award for the best new-comer in Bollywood but she simply disappeared after one movie. Her movie 'Cocktail' was a super-hit but she was not seen after that. We wonder what she has been up to since then.
2) Gracy Singh
Gracy Singh became India's sweetheart for her incredible performance in 'Lagaan.' But after that she gave flops after flops. One could argue that she was also there in 'Munnabhai' but her role was so confined that it could have been done by anyone else too.
3) Sneha Ullal
When Sneha Ullal came in the movie 'Lucky, No Time For Love' many people suggested that she looked almost exactly like Aishwarya Rai. The movie was a great hit, mostly because of Salman Bhai, but it appeared that her lucky streak ennded after that. She did a few regional movies after that but disappeared from the Bollywood scene.
4) Sonal Chauhan
Starring against Emraan Hashmi in 'Jannat,' Sonal Chauhan instantly rose to fame. Half of India was going around singing 'Zara Si Dil Mein De Jagah Tu' while she completely disappeared after the movie.
5) Bhumika Chawla
Bhumika Chawla was another actress who rose to instant fame after she appeared in the movie 'Tere Naam' but then went to do more of South Indian movies. Yes, she is a star in the South-Indian film industry but she could not survive in Bollywood after her one big shot.
