Littlefoot, here is the uncut hell footage for All Dog's Go to Heaven hell scene. Keep in mind some of the audio is not that great, but this was cut from the film after test footage and never released to the public: https://www.youtube.com/watch?v=Gr7khtV7GAs
It was in Bluth's vault, but somehow was stolen. As for the Land Before Time, I have read and seen a few pencil tests of the lost footage, but I doubt it will be released as well. It was a lot of screaming with the younger dinos found to be too disturbing for younger viewers. The concept is interesting, but a lot of Bluth stuff is too dark for the youngest viewers. I have read transcripts and some discussions on it as well.
