If I were you I would wait for a review of this particular release before buying it. The Terror is known for getting very inferior "PD" release and I'm not 100% sure this one will be different. Better to wait and see than buying another useless release.
Achim as I told you by PM this is some screen captures I took this morning from my DVD of The Terror (sorry no Blu-Ray reader on my computer)
Achim, if you're interested in seeing some Blu-ray captures:
According the review at DVDTalk they didn't use the most ideal source (original negative, kept really close by whoever owns it; apparently not lost as RogervCorman claimed).
