I have a HD 1080p rip of the 1st two Jungledyret Hugo movies with soft English Subs that I gotten ahold of awhile back from a Twitter user.
I could probably rip the subs on their own and send them to you if your still interested
If there's anyone on here who's able to translate the whole film from Danish to English, feel free to respond with your contact Discord or Telegram
I'll be willing to pay a good amount of money to have a quality fansub of War of the Birds that can be enjoyed by everyone. When a English Fansub is made, the .SRT of the sub will be hosted on Internet Archive along with Subtitle hosting sites so that everyone can have access to a English Sub of the movie including animation reviewers and casual fans of world animation.
While the full movie is no longer on YouTube, there's a full rip of the Danish version of the movie straight from the Danish DVD release on Internet Archive
With the whole movie on Archive.org, this should make it alot easier for Fansubbers to aquire the movie for the purpose of creating a fansub
