> It's very easy to see that this trend has developed and accelerated over the last 30 years. In 1981, 7 out of 10 of the year's top-grossing movies were original material. In 2014, it was 1 out of 10. Most articles on the subject tend to treat this as a mistake. The assumption is that Hollywood executives are greenlighting these projects because they're "safe". I'm really not convinced by that. Big-budget movies are a business, and are more expensive than ever. If you're going to be looking at the top 10, then yes, you're going to find 'safe' titles. A better analysis would be looking at all movies.
