Queen of Blood

The year is 1990. An alien species makes contact with Earth through radio transmission, notifying of an imminent visit. Alien ship crash lands on Mars, and a rescue team is sent out from Earth. (The plot thickens! :) Eventually a surviving female is located and brought on to the human ship. The female is light green with an amazing hair-do. After some unsuccessful attempts by the human crew to feed her, she is more or less left to herself... (imdb)
