Thanks, @OttoKerner. I do have all movies in their own folders, so that part is all good. I love the name of the ‘Plex Dance’ you reference, so I’ll give that a try in a few days if no luck. In the meantime I’ve added the official poster manually (just so it looks nice for my sister; she’s living overseas and is a musical theatre professional, so will love the show), which is fine for now.
