This came out on 1987, is directed by John Carpenter and even has Alice Cooper as a homeless zombie.
I love this movie because it’s a “devil movie”, but also has a sic-fi bent to it. A cylinder of green goo is found under an old church, people die, weirdness happens and a group of scientists and student try to save the world. It’s really worth it for a good time.
Not only is the trailer here, but so is Siskel & Ebert’s original TV review of the movie. Now, they really hated the movie, but I added it here because well, I love Siskel & Ebert even when they were wrong.
