Spokesman at Press Conference: Ladies and gentlemen of the press: As you know, the first attempt to send a spaceship to the planet Mars was made six months ago. We knew that that ship, the Challenge 141, had reached its destination, but that's all we knew.

Highly enjoyable!!!
29 September 2004 | by See all my reviews

It! The Terror From Beyond Space is simply one of the best B-movies from the 50s. This film would actually be considered a classic (rather than just a cult classic) if they just took out one of the parts of the movie where the zipper on the creature costume's back is clearly visible for about two seconds. The idea that inspired the later-on Ridley Scott thriller ALIEN (1979). A crew of astronauts from Earth are on their way home from Mars, where one of their crewmen was later strangely found dead after they went exploring. On their way back, they realize that a horrible Martian creature that feeds on blood has stowed away on their ship, and they won't be reaching Earth for DAYS!!! Highly thrilling and enjoyable, especially if you watch it with friends at night. Also recommended is THE ANGRY RED PLANET (1960) which is another early sci-fi film, with plenty of flaws.

Grade: 9/10

MPAA Rating; not rated

My Rating: Ages 7 and up (terror, some violence)
