'Not of This Earth' is a quickly made, low budget, R rated, sci-fi movie. It's made very much in the style of the B movies of the 50s and 60s except for the R rating. The R rating comes from several scenes of topless women and some sexual activity. The star of the film is Traci Lords in her first role in a non-porno film. It is also supposedly the last time she appears topless in any film. I'm sure this is one of the big attractions of the movie to a lot of viewers. She did surprise me though by her acting. It really wasn't bad. There are several scenes that were put in the film of other topless, big breasted actresses. These scenes weren't really necessary to the plot but I doubt that many of the male viewers will voice an objection to them. At the beginning of the film while showing the opening credits, there are a lot of exciting scenes shown quickly. These are not in the movie. Don't expect to see them again. Although this is not made clear or pointed out, they are from other films. It still is an interesting and fun movie and has some pretty good scenes of it's own. The film has plenty of mistakes and bloopers to look for that were left in due to the low budget. I saw this on a DVD that also had a version with commentary going through the film with you. I found it very interesting and recommend that you watch this commentary version after watching the movie. 'Not of This Earth' is a fun movie that combines some light comedy, horror and sci-fi. The movie is not meant to be taken too seriously. It's best viewed by a non critical eye with the intent of just having a good time. This can be a really enjoyable and fun modern B movie if watched in the right frame of mind.
