I know there are a lot of fans of these 1950s-1960s Japanese science fiction movies out there, and I am sure that they will find plenty to enjoy about this particular one. As for me, I find I like more the *idea* of enjoying these movies than I actually do. That's because I find a lot of them to be somewhat stiff and slow. But I admit that I found "Battle in Outer Space" somewhat more enjoyable than I expected. Most of the special effects aren't that bad for this period of science fiction motion picture cinema, with some impressive model work, sets, and other futuristic depictions of the far off future of 1965 :-) Even the shabbier special effects have a charm that you don't usually get with modern special effects. Also, some of the action sequences are directed with a little punch to them, generating some excitement.However, most of this action takes place in the last third or so of the movie. Up to that point, the movie suffers from that aforementioned problem of being stiff and slow, though I admit it isn't as severe as some other examples of the genre. There are also a few plot points that are either very unclear or not clear at all. (Though I see that the movie was slightly cut for American viewers, which might explain these murky details.) As I said, if you are a fan of these movies, you'll probably find "Battle in Outer Space" to be fun. If you are not a fan of the genre, or are still dipping your toe in the genre to see if you'd like it, you'd probably be better off watching something else.

This movie has pretty decent special effects for its era and might be quite good. The fundamental flaw is the incredible nativity of the plot and stupidity of the "actions" of Earth soldiers. A little hint here: You should never allow troops to be lead to the war by the nation who just lost the war. The combat scenes are stupid and overall "plan" of Japan lead Earthlings is basically nonexistent. I do mean the combat scenes are painfully stupid. This has degraded the movie so much! I think it still worth to see how great special effects could be made before the CGI era. They are really really good. But the plot should be written by someone completely else.

I thoroughly enjoyed this film. It is certainly paced slower than modern sci-fi movies, but the action moved along at a good pace nonetheless. The backgrounds, matte work, color and special effects were very impressive.The one conceivable flaw was that there were no stand out actors or personal relationships (no love interest as there was in the original Godzilla). This may have been intentional as the story meant to emphasize a global effort against a ruthless and cruel invader.) I would rate this on the upper scale of Toho's scifi efforts (anotehr under-rated, under-viewed film would be "H-Men").If you are a kaiju fan you will not be disappointed.

Dr. Immerman (played by Harold Conway)is my Grandfather and I this movie is great!! This fabulous movie is guaranteed to please any Sci Fi audience with lots of action & special effects and it captures the magic and nostalgia of the cinema of days gone by!
