Haha, yes I think I remember you updating your log on a Thursday even when it was Christmas day
Doing a part-challenge in Esperanto is brave. Reading matter will definitely be easier to come by than video/audio, though Esperanto books do tend to be expensive (I guess because of the small print runs).
In addition to Project Gutenburg, there are a few other sites with free stuff online:
Don Harlow's website - Don Harlow died some years ago, but the website where he collected Esperanto poems and short stories is still online. There's a real mixture of stuff there, some original and some translated.
This website has a collection of pdfs to download, mostly translations from well-known European authors. There are a few things in there like 'Murder on the Orient Express' that are probably quite easy to read.
Claude Piron was well-known Esperantist who died a few years back. He wrote original Esperanto literature including the famous book 'Gerda Malaperis' which forms the basis for several Esperanto courses. It was written for beginners, so the story starts off with very simple language and progressively gets more complex as the story goes on. It might be a good place to start as an Esperanto reading warm-up
He also wrote original crime fiction under the name 'Johan Valano', the most famous of which may be 'Ĉu ŝi mortu tra-fike". The slightly crude play on words in the title doesn't translate well into English, so I'll leave you to figure it out.
The only Esperanto association I'm aware of that sells e-books online is
FEL although to be honest, most of them aren't any cheaper than real books. 'Ĉashundo de la Baskerviloj' is only EUR 6 though and a good translation.
The Esperanto Association of Britain sells second-hand books on
ebay. Turns out today is a really bad time to link to that as our office staff member has been on holiday, so there isn't anything online, but normally I think she puts about 10 books up per week which all start from 99p. The association gets masses of duplicate second hand books as people die and pass their collections on to us, so it's normally a good way to pick up some bargains.
Esperanto film isn't really a thing, so recommendations are harder to make here.
Films which do exist are:
Angoroj- The first original film in Esperanto.
Incubus - The Shatner one, although the Esperanto is very bad in this.
Gerda Malaperis - The film of the book by Claude Piron. Might be a good place to start
It's hard to know what will count for the Super Challenge really. The World Esperanto Association (UEA) has
Youtube channel for example that has some film of fairly highbrow lectures given at congresses, for example, but not sure whether that is a valid 'film'.
There are definitely some audio-books, which ought to count:
La eta princoSmall collection on LibrivoxSome suggestions for podcasts...
MuzaikoVarsovia VentoĈina radio en Esperanto - Perhaps a good one to listen to non-European accents in Esperanto
Radio Verda - no longer making new material, but think you can still download the old ones
Radio Vatikana - Lots of material but you have to be very interested in following the activities of the Pope
