Some keyboard shortcuts I forget:

You can use .nfo files instead of, or to enhance the data Kodi gets from databases like The Movie Database.

They can just include a link to your movie on IMDB, or can contain XML.

The best way to get rolling is to use an online database to get all the data it can. Then from the settings you export your data as individual files that will be in the right place (in each films' directory) and you can make any needed changes (there'll be a bunch of misidentified films).

I have a file called movie.nfo in my ~/Templates directory that I use for new entries. Contents:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<movie>
	<title></title>
	<originaltitle></originaltitle>
	<sorttitle></sorttitle>
	<plot></plot>
	<uniqueid type="tmdb" default="true"></uniqueid>
	<uniqueid type="imdb" default="false"></uniqueid>
	<country></country>
	<director></director>
</movie>
