ELIF: why does it take upwards of a year to make a single movie, but around a year and a half for a 20 episode, 45 minute an episode TV season?

There are a few reasons.

* A lot of the work done for a series is only needed once - hiring crew members (including actors), finding locations, making props. You don't need to do all that for every episode.

* You can also shoot multiple episodes at the same time - usually, a movie will have just one or two directors and a handful of writers, while TV shows have a multiple directors and plenty of writers who can share writing and directing responsibilities.

* Movies have a much higher risk and gain the TV shows. A lot more money is invested in the movie and in marketing, in expectation of a lot more revenue. Therefore a lot more time and work are dedicated to the movie, for example the amount of post production and CGI in a typical film is far greater than in a TV series.
