"Teenagers from Outer Space" (1959)
This was a really entertaining stinkeroo, supreme MST3K material. I even found myself cracking jokes out loud, even though I watched this movie alone. Basically, this group of aliens that all look like Frankie Avalon are looking for a place to grow their lobster monsters, and they decide on Earth. However, one of them was reading a book that made him feel compassion for life, so he runs away from the group and is chased by the meanest of them, Thor, who wields a strobe-light gun that turns people into skeletons. Lots of murder, bad effects, and even a few sexy double entendres. Something I enjoyed, but never want to see again.
