Older horror movies you should check out!
April Fools Day (1986)
FROM IMDB: Nine college students staying at a friend’s remote island mansion begin to fall victim to an unseen murderer over the April Fool’s Day weekend, but nothing is as it seems.

From the shrieks to the scary music, to the jump scares, this film screams 1980s horror! So, a bunch of college kids go out for one big blow off weekend at a friend’s place on the islands when people suddenly go missing. We’ve got young people having fun, a location that they can’t escape from, a bizarre personality change from the main character, and a twist at the end that was NOT what you’d expect from an 80s slasher film. You might recognize some of the actors including Thomas F. Wilson (Biff from Back to the Future) and Deborah Foreman (Valley Girl). This one is permanently planted on my annual October Halloween movie watching list.
The Relic (1997)
FROM IMDB: A homicide detective and an anthropologist try to destroy a South American lizard-like god, who’s on a people eating rampage in a Chicago museum.

A monster that feeds (and mutates) off human brains and South American leaves is about to take over a city if it escapes the museum to which it is encompassed. I liked the aura of this film, and the fact that it takes place in an enclosed (albeit large) space makes for a better film than if the being was running amok over an entire city. The characters are pretty solid (Penelope Ann Miller, Tom Sizemore, and Linda Hunt lead the cast), and the scares are plentiful. If you are a fan of monster movies, do yourself a favor and give this one a try.
DeepStar Six (1989)
FROM IMDB: A team of navy personnel stationed at a temporary base at the bottom of the ocean and tasked with setting up nuclear missiles discovers a huge underwater cavern which houses a giant prehistoric creature.

From director Sean S. Cunningham (Friday the 13th), this little cult classic has always been one of my favorites. The crew of an experimental underwater nuclear base crosses paths with a sub-aquatic monster that begins targeting them for extinction after a mishandled test of their equipment. The film is pretty intense, and some of the deaths are quite gruesome. You really started wondering how they were going to kill the thing and if anyone would survive. The film stars some recognizable faces such as Miguel Ferrer, Taurean Blacque, and Cindy Pickett. Fans of Jaws or other aquatic monsters should give this one a go. It is highly entertaining!
