And even a RomCom with no big stars like Last Christmas cost $30 million. It isn't movies are not being made there just are not enough people wanting to see them to fill the box office. Of course even in the golden age he is referring to in the title the big box office hits were movies like Jaws, Star Wars and Towering Inferno.
The kind of movies he wants are still being made, and probably at greater rate than ever they just aren't making the big screen. Theaters make their money selling $12 tickets and twenty five cents worth of popcorn for $10. It typically cost me about $50 to take my family of three to the movies. I won't pay that for some dark artsy movie that may or may not be good. It is simple economics that are cause these changes.
