It tells you something about the order of priorities in George Pal's production of Conquest of Space that the opening credits don't list any of the actors in the movie -- on one level, it's almost as though we're to take the movie as a sort of documentary of things to come, and that's how it seems, until the backstories on two of the characters come to the forefront of events onscreen. The result is an awkward mix of sci-fi/docudrama and sci-fi melodrama, sort of Robert Heinlein's juvenilia sensationalized. The movie's problems notwithstanding, the film has gotten first-class treatment on this DVD, with a beautiful transfer that runs circles around the television showings that the movie received in the 1960s and '70s. The letterboxed image (1.85:1, with 16 x 9 enhancements) glitters, so much so that parts of it look almost 3-D, and take the clarity right up to the limit of the special effects' boundaries. The sound is mastered at a somewhat low volume level, but is otherwise clean and sharp, and pumps up nicely through speakers. There are no extras, not even a trailer -- but the effects look so good, and the movie is so entertaining (if not the profound work of speculative fiction that was intended), that it's thoroughly diverting on its own. The disc opens on a simple, easy-to-use three-selection menu that goes to a second layer for the chapter selections; the 80-minute movie has been given 14 chapter markers, which are more than adequate to outline the fairly simple plot.
