Very well executed

Pretty good movie overall. First half was nothing special but it got better as it went along.

It was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

When I'm feeling down a bit, I love to watch old B-Horror movies. This one has wonderful elements. It has a cast of characters who confront an invasion from space, zombies, a pretty boy macho soldier (John Agar), the pretty daughter of the scientist who becomes an intermediary to the aliens, a cowardly guy with a pencil thin mustache, John Carradine, invisible people who seem to drag their feet through soft earth, stock footage from various disasters (including one where a man in a Nazi helmet runs along a wall toward a bombed out building). What more can one ask for. There are sonic ray guns, failed attempts, fights, romance, tough talk, etc. This one is less tacky than some of the offerings and it has a good heart. I wondered why the aliens felt the necessity to announce their coming. They could have just moved in and avoided a lot of trouble. I guess they were just trying to avoid using their resources, but they really underestimated the resolve of cold war America (of course, the rest of the world was involved as well). One other issue is the ease with which this little band of rebels was able to put together weapons within a few minutes. But, as is the case with most of these movies, better left unquestioned.

Aliens, contacting scientist Adam Penner (Philip Tonge), inform him that they have been on the moon for twenty thousand years...Why is science fiction always better with John Agar? And why does it strike me as odd that they refer to the zombies in this movie as the "walking dead"? I thought this was a more recent term, but it apparently is not.Overall, you know, the movie is cheesy. The invaders are "invisible", which is just about the easiest kind of aliens that can be shown on screen. I do appreciate they had the newspapers making fun of the idea, because it is pretty silly and sounds like a way to cut the budget.

No, this movie did not "inspire" Ed Wood.Plan Nine From Outer Space may have been released after this film, but it was shot at least two years prior to this one (around 1956), and probably was written one or two years before that. Ed Wood spent some time trying to get the thing made/gathering money together, and then after the film was actually completed, PNFOS sat on the shelf for quite a while before it got minimal screen time from a barely interested distributor in 1959 at the bottom of low budget double or triple bills.Having said that, I highly doubt that the makers or writers of this film actually saw PNFOS prior to putting together Invisible Invaders. PNFOS was just that ignored and low profile before it achieved its notorious reputation as "The Worst Film Ever Made," which did not take place until the early 1980's.I'm sure it's just a matter of pure coincidence, or let's be a little more generous and say zeitgeist among 1950's low budget science fiction/monster movie makers, and leave it at that. There were many other plot threads repeated in these low budget genre pictures during that time. There was the "traveling to another planet and finding the underground civilization of hot female beauty pageant winners in high heels and showgirl costumes" plot, or there was the "astronaut goes up into space and returns to Earth as a mutated monster" yarn. How about the similarities between the Steven King/Frank Darabont "The Mist" and the 1963 Grade-Z cheapie "The Slime People"? Many others I could mention.Although as far as George Romero goes, it's quite possible that both Invisible Invaders and Plan Nine From Outer Space did make some contribution towards the idea behind Night of the Living Dead. Both films were occasionally screened on late night local TV broadcasts during the 1960's on various local channels around the USA. But, I'm sure Romero would deny it.

The movie was done on a shoestring budget ,for all that demands a lot of money (the adventures of the aliens on their planet,in Space ,on the Moon) is told by a grating voice over which explains everything to us -and another one for the voice of the invader(s)- and sometimes becomes preachy,urging the countries of the world to get together and to stop building their atomic bombs ,which makes the flick look like a rehashed "the day the Earth stood still" as far as moral is concerned).Besides the main idea of the screenplay was borrowed from the highly superior "invasion of the body snatchers" which I urge sci-fi buffs to see immediately if they think that the genre produced only lousy movies in the fifties.The last scene sells the fin de decade audience universal utopia.
