My bargain of the sales was Pitch Black from DVD+ £7.99 delivered, marvellous. However to tell the truth I have only just gotten around to watching it! And I'd completely forgotten where the layer change takes place, probably because it is in such an obviously perfect place, Chapter 10 to be specific just as the planet is plunged into "Pitch Black" by the eclipse. You dont see the change obviously (it is Pitch Black after all), but you do hear it not that it detracts from the movie, but still and getting to my point (finally), why cant all changes be dealt with in the same straight forward manner? Si PS. And why has it never been released in the UK cinema, what a shame. I for one would happily pay the fee to view this cracker of a movie on the big screen..
