Early predictions of movie success: The who, what, and when of profitability

Published in Journal of Management Information Systems (JMIS), 2016

This paper investigates the predictability of movie success (profit) utilizing features (variables) strictly available during the pre-production stage. We investigate the features that are important to the prediction problem and propose a "Movie Investor Assurance System" (MIAS).
