The Day of the Animals is a 1-disc edition with 2 versions of the film on the disc, with only one version worth watching. The theatrical cut of the film (under the resissue title - Something is Out There)is in the proper 2.35:1 Panavision aspect ratio, but is taken from an archive print which bears signs of the ages.
However, it is very watchable if not up to the pristine standards expected of brand-new film to DVD transfers. Apparently the original negative has been lost, and this is the best we can expect. It is missing a brief few seconds of dialogue (which you can see in the TV print), and has a bizarre black screen (for about 1 minute) right after the credits (so fast-forward).
The TV print is an awful 1.77:1 detail extracted from a panned-and-scanned version of the film. This is to say, they have taken the original 2.35:1 image, cropped it by 40% to fit an old 1.37:1 TV, and then further chopped off the top and bottom to make a fake 1.77:1 16x9 TV image! This version has less damage, but is the worst possible version of the film to view. The extras are all fine (commentary, documentary, trailers etc).
Both the Grizzly and Devil Dog discs are first class, the Devil Dog being a two-disc set.
