With the news (new to me as I don't particularly follow film news) that Ridley Scott has done a new final director's cut of Blade Runner http://www.nytimes.com/2007/09/30/movies/30kapl.html?ex=1348891200&en=78f16e2eb381c7f2&ei=5124&partner=permalink&exprod=permalink comes thought of the old anomaly that Peter Nicholls, when he came to talk to OUSFG in I guess 1982/83, had clearly seen a different cut from the one released, since he had seen 'the Unicorn scene'. The conversation was obviously a bit weird since he didn't realise we had seen something different (i.e. what do you mean it's ambiguous, it's bloody obvious). Wikipedia mentions an early workprint, but it is rather surprising he would have seen that to review. Perhaps he went to a cinema in a parallel world. As we all know you can never go into a parallel world for anything important, but seeing different versions of films is one of the things allowed.
