Yes, I read once that Bluth had planned on things being a bit more realistic whereas blood and general things in the gore direction were concerned. Not that I'm sure of any of these things, or that even the gore was going to be anything truly drastic. I also read that some of the audio of the film had to be rerecorded multiple times to make the children's screams less horrific-sounding. May sound weird to some, but I would honestly like to hear some of the outtakes just to get a good glimpse of what Mr. Bluth had in mind.
And in a more hopeful line of thinking, with the anniversary coming up, it would be nice to see an uncut Land Before Time available on DVD...
