“In space, no one can hear you scream,” went the tagline for the original “Alien” in 1979, a terrifying thought on multiple levels. There may indeed be a scientific rationale for a space scream to be inaudible, but isn't it scarier to simply realize nobody’s around to hear you? That was the case for Sigourney Weaver’s Ripley, once she became the last one standing against the fearsome Xenomorph. Nobody could hear her scream — nobody human, that is — because, duh, everyone was dead.

In any case, hearing won’t be a problem here on Earth at any multiplex showing “Alien: Romulus,” the much-anticipated new installment to the “Alien” franchise (not a sequel, but we’ll get to that in a minute.) This is a very big, very (very!) loud, very jumpy horror flick, and the screams will come, and they’ll be audible. Which is precisely what “Alien” fans are surely waiting for.

And speaking of Ripley, no, neither she (nor Weaver) are present in this new version by Fede Álvarez, closer in feel to the horror roots of Ridley Scott’s original than James Cameron’s more action-focused 1986 “Aliens.” But now we have Rain Carradine, played by rising star Cailee Spaeny (“Priscilla”), a new-generation Ripley in everything but name.
