Blimey can you?! I've been having a go at a few bits from the TV version but I really can't make out anything comprehensible.
Please post as much as you can, if you say exactly which bit of which episode it's from, I can add sound clips to prove it, too! Personally I'd be most interested to find out what's being said in the meteorite room when Dad explains things to Bunting - I could make out part of this, where Daddy goes "It is the language of your world! You must be able to read it!" but the rest just seemed to be a mush. Also, those bits where the Thin Man is stalking the kids through the woods at the end, he does quite a lot of talking there...
I wonder if our Thin Man from on here already knows all the answers to this from his conversations Peep-peep himself?!
I'm sure you're not really supposed to be able to tell what they're saying - there seem to be some incomplete sentences bunged in, and there's contractions used in the dialogue - reading consultants would never have let them get away with that in 1971!
Oh, and just to add to what was in that "They're just talking backwards!" thread - in the third clip, with Daddy in the spaceship, I've realised what he's actually saying is "the meteorites for himself" - they only used the last half of the sentence, so surely you're not really supposed to be listening to it.
