In the world of moviemaking, it’s generally considered good business to release the movies you make. After all, they can cost tens of millions of dollars to produce, and (pardon me for getting overly technical here) selling tickets for the general public to view them can help recoup that cost. Streaming TV has changed that calculation a little. Now films are sometimes made not to sell tickets but just to beef up entertainment libraries for monthly subscribers.
