Following the success of Kaun Banega Crorepati, there were numerous clones which failed to take off. For instance, Anupam Kher and Manisha Koirala together hosted Sawaal Dus Crore Ka which tanked. Govinda tried in vain to host Jeeta Chappad Phad Ke .
Madhuri Dixit hosted a game show based on match making called, Kahin Naa Kahin Koi Hai, which I doubt people even remember. Mukul Dev also tried hosting Fear Factor, and the only people who were frightened were the audience who tuned out of the show.
