Indian film industry is one of the biggest in the world. A considerable number of movies out of the all movies released in a year are considered as hit movies. In a cinema hall k tickets are available and for a hit movie more than k people give demand for a ticket to watch the movie. To earn more profit in that environment, in this paper an auction based truthful mechanism is proposed for selling all the tickets of the cinema hall and it is shown that our auction based scheme is significantly better than the existing scheme in terms of the total income earned per annum. Our scheme could be applied on any film industry.
