Night of the Comet movie trailer

Movie trailer to Night of the Comet (1984), starring Catherine Mary Stewart, Kelli Maroney
 It’ s the first comet to buzz the planet in 65 million years. And everyone seems to be celebrating its imminent arrival. Everyone, that is, except Regina Belmont (Catherine Mary Stewart, The Last Starfighter) and her younger sister Samantha (Kelli Maroney, Chopping Mall).  These sisters are two Valley Girls who care more about fashion trends than astronomy. But at daybreak, the girls discover that they’re the only residents of Los Angeles whom the comet hasn’t vaporized …. Or turned into a zombie.  So, they do what all good Valley Girls do...they go shopping! But these gals flee with killer zombies and blood-seeking scientists in hot pursuit!
