What do you mean ?? The Directors cut hasnt been released before in the UK - If you mean differences between the normal and directors cut - there was about 3 mins of cuts (over 200 cuts so i've heard) - You can get the Directors cut from Australia for around £10 including P+P Thats where i got mine from months a go.
Got it slightly wrong only over 150 cuts

I think the R4 version may have a few more extras, than the Warners UK release, and is in a proper Amaray case, but other than that, they're the same.
However, the uncensored Director's Cut HAS already been on UK! It was on FilmFour about 4 months ago!! Good thing is, that the film was the entire uncensored Director's Cut, in widescreen, and I didn't need to pay Warner's a penny!
