since this DVD came out in May of 2002 I won't be talking too much about the actual movie, aside to say it's easily one of the best that Universal made in the 50s. the print looks great and the sound is good. buy it here.
mostly I want to talk about the extras, starting with movie historian Tom Weaver's excellent commentary. I rarely listen to commentary tracks, since most of them are not that informative (maybe I've listened to the wrong ones, hello GIANT BEHEMOTH) but Tom does an exemplary job at talking about every part of the movie, from Ray Bradbury's two treatments for the scripts to the actors, directors, effects and locations used for filming. he also had a good sense of humor about some things but never treated any of the subject matter as a joke.
the other great extra is (I believe) a TCM produced documentary called "The Universe According to Universal" and it talks about many of the classic 50s sci-fi movies and aliens. not too long and not too short.
of course, the DVD itself has one glaring problem- that cover! while it's a cool looking alien, nothing like that appears in the movie at all. ever. did the moron who designed THE VALLEY OF GWANGI make this cover as well?
and for the record, I am glad they showed the xenomorphs in all their one eyed glory.
