Dan [O'Bannon] said, "Somehow, the monster has to get on board the ship in a way that'll amaze everybody." And so I woke up in the middle of the night and I said, "Dan, I have an idea." And he said "What?" And I said "The monster screws one of the people." He says "What? What are you talking about?" I said, "He jumps in his face, plants a tube down him, inserts his seed in him, and later it comes bursting out of his stomach! And Dan goes "(Gasp!) My God, that's the most amazing thing I've ever heard! No one's ever seen anything like that."
