Abstract: Prediction of revenue before a movie is released can be very beneficial for stakeholders and investors in the movie industry. Even though Indian cinema is a booming industry, the literature work in the field of movie revenue prediction is more inclined towards non-Indian movie. In this study we built a novel hybrid prediction model to predict worldwide gross for Bollywood movies. Bollywood movies dataset is prepared by downloading movie related features from IMDb and YouTube movie trailers which consists of 674 movies. K-means clustering is performed on the movie dataset and two major clusters are identified. Important features specific to clusters are selected. The proposed hybrid prediction model performs segregation of movies into two clusters and employs a prediction model for each cluster. Prediction models we tested included various basic machine learning models and ensemble models. The ensemble model that combined predictions from support vector regression, neural network and ridge regression gave us the best result for both clusters and we chose it to be our final model. We obtained an overall MAE of 0.0272 and R2 of 0.80 after 10-fold cross validation.
