Yeah, they seem a little bit rare (I think it's only the separately released Blu-rays from most European countries including UK (Momentum Pictures but not HMV Grindhouse version AFAIK), USA (Genius Products) & Australia that have the full fat versions. Lions Gate's
Tarantino XX: 20 Years of Filmmaking release seems to have the full fat version of Death Proof.
I think the extra violence suits the films you'd never know it was the extended version. Listening to the directors they were forced to cut the film down with censorship too.
I don't think I ever watched the Grindhouse versions bit late now maybe.
My favourite tat releases:
That's a film can from Australia and the petrol cans are from Germany.
I don't know for sure who owns these 2 films since Weinstein ended up in the pokey. Lantern Entertainment bought TWC's Inglourious Basterds, Django Unchained and The Hateful Eight and it looks like they also own Dimension's Grindhouse (the combined versions of Death Proof & Planet Terror).
Lionsgate/Anchor Bay Entertainment look to have the home video distribution rights now for Death Proof & Planet Terror.
I mentioned in another thread that they altered the Red Cross symbol in the hospital scenes in Death Proof and they also altered it in Planet Terror colouring it black too so as not to break the Geneva Convention. You can see both are red in the extras on both discs. Not sure if I noticed that at the cinema or not.
