Yep, Alien!
A crew member touches an egg, which immediately opens, and he ends up with a creature attached to his face.
The crew are betrayed by their employers and a mate, who is actually an android, who has instructions to sacrifice them all, if necessary, in order to capture an alien.
The crew battle to survive, especially the one played by Sigorney Weaver, who survives because she keeps her cool and thinks on her feet.
