You can add meta data tags with such information to your own media files, using a third party tool, like Subler. After tag editing, remove and re-add the file(s) to your library for updated library presentation. ‘Director’, ‘Cast’ and ‘Screenwriters’ are supported tags there. Subler supports more tags than the Apple TV app is able to show back, and not all available tags are relevant to video files (some tags are more for other types of media files). Subler has integration with online look-up, so for select content, you might be able to use tags that other people have already submitted. Edit manually as needed. For release date, if added, using the ISO notation YYYY-MM-DD, so that other applications can easily understand it. Note that Media Kind: Home Video will show less of the tags in the TV app than Media Kind: Movie.
