No, not the Alien you know and love. Not even Alien. You probably don't even know about this one.
Alien 2: On Earth is an unauthorized Italian ripoff of the Ridley Scott classic. I'm not sure about the budget, but I assume this was made for about twenty bucks, and that's being generous.
Don't watch if cheapo effects scare you. YOU'VE BEEN WARNED.
Yeah, the trailer kind of speaks for itself. The film itself is very obscure, and was pretty much impossible to find until they released it on Blu-Ray.
