It was announced a while back, but in case you missed it (like I did):
Grindhouse is being released as two seperate DVDs. Planet Terror will include everything from the beginning (including the Machete trailer) to the end of PT’s credits, and Death Proof will include the “half time” trailers, and the whole film (probably the longer version that ran at Cannes).
That’s what was announced, at least. However, checking Amazon, I see nothing in either films DVD release information entries that indicates that the trailers are there….and it appears that Death Proof is being released FIRST.
So, those of us who saw Grindhouse in the cinema when it briefly played are the only ones who will have gotten the true experience.
Time to search for a bootleg on Bittorrent, methinks.
