15. An Amazing Coincidence One of the studios with the most on-screen diversity — it released “Trainwreck” and “Straight Outta Compton” (if also “Ted 2”) — and with some of the most female directors is Universal, which, as of early December, had gobbled up almost 24 percent of the year’s market share.

16. Most Ignored Truism “There’s a myth in the business that young males drive the box office,” Tom Rothman, the chairman of Sony Pictures Entertainment’s motion picture group, told The Hollywood Reporter in November. In this same interview, Alan F. Horn, the chairman of the Walt Disney Studios, tried to make it simple: “There are variables that do affect what one pays any performer. Angelina Jolie, for example, got a lot more money for ‘Maleficent’ than Daisy Ridley did for ‘Star Wars,’ but they’re both women.” (Gee, thanks, Alan!)

17. Most Complex Hurdle As of Dec. 7, seven out of 20 domestic top-grossing movies released this year had female-driven stories, according to the website Box Office Mojo. By contrast, five out of 20 female-driven stories topped the international market, which accounts for some 70 percent of the industry’s revenue. This may look bad, but the numbers appear marginally better than they have in recent years.

18. Most Interesting Apology (tie) On Nov. 18, The Hollywood Reporter disgorged a 1,200-plus word apology for not including any nonwhite performer in its Oscar actress round table. Soon after, the director Alex Proyas and Lionsgate apologized for the lack of diversity in the cast in their new movie “Gods of Egypt.”

19. Going, Going, Almost Gone Quentin Tarantino shot his latest, “The Hateful Eight,” in 70 millimeter, and the film is slated to play in almost 100 theaters that, like most of rooms across the country, now usually use digital projection. Whatever you think of Mr. Tarantino, try to catch “The Hateful Eight” on film so you can see for yourself how the industry-enforced switch to digital has radically changed movies.

20. Best Advice for Movie Lovers In August, the scholar Wheeler Winston Dixon sounded an alarm: “If you go on Amazon and you see some great black-and-white film, and it’s going for $3, or any kind of foreign or obscure film, buy it, because it’s going out of print, and they’re not going to put them back into print.” Tens of thousands of films that were on VHS never made the jump to DVD or to Blu-ray, Mr. Dixon warns. And the brave new world of downloads (a.k.a. electronic sell-through) — well, tune in next year.
