Queen of Blood (1966)

John Saxon and Basil Rathbone star in this campy tale about an alien ship that crashes on Mars and the astronauts from Earth who fly in to assist… not realizing the alien they’re trying to save is a space vampire! Even worse, the alien vampire queen stealthily lays a bunch of gooey eggs aboard the rescue ship, knowing that Earth will be the perfect hunting ground for her kind to repopulate (no surprise, Queen of Blood is often cited as an influence on Alien). The movie ends on a spectacular note of doom, with one astronaut declaring they should destroy the eggs, while another takes a more Weyland-Yutani point of view: “Scientists from all over the world have been waiting for us to bring back something living! They’ll keep them under control! They’re scientists, they know what they’re doing!”
