I just wanted to point out some errors/inaccuracies with the Region All/0 Powerhouse Films Limited Edition release of John Carpenter's Vampires.
1: The "Making of John Carpenter’s Vampires" featurette listed in the comparison for this release, is actually 6 brief featurettes and not 1 big doc but there is a Play All feature. The titles and runtimes of the featurettes are as follows:
Behind the Scenes (6mins 10secs)
James Woods Interview (2mins 25secs)
Daniel Baldwin Interview (2mins 02secs)
Sheryl Lee Interview (2mins 02secs)
John Carpenter Interview (2mins 16secs)
B-Roll (8mins 38sec)
Play All Length: 22mins 36secs
2: The Featurettes menu is actually called "The Making of Vampires", not "The Making of John Carpenter’s Vampires"
3: With the exception of the Theatrical Trailer, which is in 1080p, all the video extras are in 480i.
4: The DVD specs for the bundled DVD copy are identical to the Bluray, except the 5.1 track is Dolby Digital and not DTS and the Isolated Score is in Dolby Digital 2.0. If you would like me to submit the full DVD Specs as a separate thread, then that can be arranged

5: Suggested update to the Overall: "Winner: UK Region All. For being uncut and having all the extras from the Twilight release, plus several additional featurettes and Part 1 of a lengthy interview with Writer/Director John Carpenter (the other half is in the Ghosts of Mars release by Powerhouse Films). Note that the French release has a documentary on John Carpenter but the film is the cut version".
6: I don't know if the upcoming standard release will also have this but the Limited Edition has a reversible cover that removes the top banner showing the name of the distributor.
7: The booklet included with the Limited Edition, also contains an interview with John Carpenter that was conducted by Jim Hemphill in October 2015 for Filmmaker Magazine. Also note that the Kim Newman essay was written by him in 2017.
