If you’ve gone to the movies lately, you might have noticed — or even purchased — one of those novelty popcorn buckets promoting the year’s big blockbusters. Maybe you dug into the gaping maw of a Dune: Part Two sand worm — or, more recently, into the hollowed-out head of Deadpool or Wolverine. Now, there are at least two popcorn-bucket models promoting the new movie Alien: Romulus .

One is shaped like the head of a Xenomorph, that most terrifying of horror-movie demons, though I suspect without the drooling retractable tongue. Another bucket comes affixed with a Facehugger, a skittering critter that’s famously fond of attaching itself to a human’s head and laying an egg in their throat. These concession-stand gimmicks may be new, but the iconography of Alien: Romulus could hardly be more familiar.

That’s no surprise; these monsters, brilliantly conceived decades ago by the Swiss artist H.R. Giger, have kept this series alive.

In recent years Ridley Scott, the director of the unimprovable 1979 Alien , has tried to push the franchise in a more philosophical direction, in movies like Prometheus and Alien: Covenant . By contrast, Alien: Romulus , which was directed and co-written by the Uruguayan filmmaker Fede Alvarez, has no such weighty ambitions. It’s an efficient and reasonably entertaining thriller that, like a lot of franchise movies nowadays, traffics more in nostalgia than novelty.
