The plot is simple, but the story line is all over the place. Bela Lugosi shows up out of right field dressed as Dracula, then disappears just as quick as he showed up (in his defense he died during this movie). It was written and directed by Ed Wood.
Now 50 years, yes 50, it is being remade and titled Plan 9. I haven't found many remakes that I like, but there are a few. That's why I give everything a shot, but this one will most likely be better than the original. From what I have seen from the teaser I'm impressed. It has zombies, aliens, some good FX, and a solid story. I wish these guys the best of luck for tackling this project and now I'm just waiting on the release date.
Here's the trailer and the poster for ya:
