This film did remind me of the kinds of ideas in Crichton's novels - especially his early medical fiction. Who would have guessed that a now-forgotten low-budget B-movie would actually end up more timely almost 40 years after its original release? I don't know of any earlier film treatments of the subject of cloning than this film - I really wonder what audiences thought when this first came out, as the plot line of the film must have seemed really wild back then. I don't particularly care for remakes - especially of good movies like this - but now would be a terrific time for a remake of this story, possibly with a better budget. As it is, the film stretches its budget pretty well, but I would have appreciated greater attention to the scientific aspects of the cloning (possibly with some special effects). Additionally, because all of the real-life politicians seem to be weighing in on the stem cell and medical ethics issues, the political aspects of the story would fit perfectly into a remake, where they could be fleshed out in greater detail. I guess this movie just has me thinking more of what it could have been than what it is. On its own level, it is a surprisingly thoughtful low-budget film that concentrates on ideas, rather than action. For that, it is well worth searching out.
On a final note, it has a ridiculous non-sequitur ending that had me giggling, but the ending seems to fit a cheap movie like this, whose filmmakers certainly couldn't afford a lot of explosions and gunfights .
