At least at the time of Red Dwarf season 5 DVD release (2005-ish?), the first pilot was still retained - hence higher quality clips used in a documentary. A shame they didn't get the rights to both and have them as extras. And to think Linwood Boomer developed the US version and co-wrote the pilots, he's the same guy behind "Night Court" and "3rd Rock From the Sun" - two hilarious shows (IMHO). At times he's onto something but a lot of the jokes, especially those ported from the original, just didn't translate.
Some YouTube channels feature both pilots. Amazed anyone had them to leak them. Hinton as Cat was pretty good, but Farrell as Cat just feels more original and not trying to do the impossible of outdoing Danny John-Jules. The actors were all rather good, but the scripts were so flat and the characters were just walking diorama parts. The 2nd pilot improves on this, partly due to changing Cat so dramatically. Both pilots are lacking but both aren't as rotten as their reputations suggest. The 2nd one might have taken off if the network bought it, but they did not.
I shall have to seek them out. Thanks for the info, fellow smeghead! :-D
