Incubus aside, what else is there that one should have seen? Just as there is a baza legolisto, is there a baza vidolisto? I'm not looking for movie recommendations, but a resource for movies that could be described as the "canon," if there is one.
This might be a somewhat opinion based answer, but anyway.
To me, making a good movie is one of the biggest challenges the Esperanto culture has. So far there are a couple of movies which are either not by Esperanto speakers or ... well ... bad. My main criteria of the quality of Esperanto culture is "Would Esperantists also read/watch/listen to it, if it was not in Esperanto?" And all the Esperanto movies I know of most Esperantists wouldn't bother to watch if they were not in Esperanto. Looking at music, this is different. I probably wouldn't know for example Martin Wiese if he didn't sing in Esperanto, but if I found his music in a different language by recommendation, I would listen to it.
The problem with movies as opposed to music, poetry, novels and stuff is, that it takes a lot of qualified people to make a good movie. To make good music, even one capable motivated person can be enough. Same for podcasts, poetry, novels. But for a good movie ... tough. Not only capable people but also equipment.
So to answer your question: No there isn't a movie canon, because there hardly are movies in Esperanto out there.
There was this attempt by the German Esperanto Association when they did a short film contest. There are some quite good ones among them. Further there is the "Teo kaj amo" short movie contest by China radio internacia. Just search "teo kaj amo" on youtube.
