I do believe it's an 80s movie, and the word "Alien" is in the title of the movie but I can't figure out what the second word is in the title.
The movie is about lizard type aliens that come from outer space and land on Earth. They find hosts and they crawl inside their mouth and take over their body. Then they go into hibernation and awake like 20 years later and they are in the 80s, but they dress like they are from the 60s.
Then a good Alien comes, takes over a hot blonde girl, and she goes and hunts those bad aliens. She destroys them then the alien leaves the hot blonde girl's body and the end.
If you know the name of this oldie movie, I would appreciate it. It's Alien _____.
