Je Leonardo DiCaprio dobrá investice?

This thesis researches whether there is an effect of casting Leonardo DiCaprio or other star actors in a film on the revenue of the given film and what the effect is, respectively. The data consists of a sample of 905 films screened between 2005-2015 in the United States of America and Canada. The results estimated by the method of least squares indicate that star actors have a positive influence on revenue. The presence of a financialy successful actor means 12% increase in revenue. On the other hand, Oscar-awarded actors influence revenue to a lesser degree. The hypothesis about Leonardo DiCaprios influence could not be either confirmed or denied. Other factors researched were e.g. budget, ratings, whether there is a sequel or director, among others. The variable with the most positive influence is budget; the existence of a sequel is the second most decisive factor.
