Even without Ripley (Sigourney Weaver), there’s still plenty of money thatAliencan make at thebox office,andAlien: Romuluscould very well set the record for the best opening weekend of any film in the beloved sci-fi horror franchise. With only 10 more days to go before director Fede Álvarez’s cinematic contribution to theAlienseries hits theaters,Romulusis eyeing a domestic debut in the neighborhood of $35 million to $50 million (perBoxoffice Pro). If theCailee Spaeny-led outer space thriller can lean into the top end of that forecast,Romuluscould have the biggest opening weekend domestically of all nineAlienmovies.

2012’sPrometheus,which starsX-Menalum Michael Fassbender, currently holds the record for the best opening weekend with $51 million. And while not doing quite as well asPrometheus,the last big-screen installment from the saga,Alien: Covenant(2017), also did respectable business during its own debut with $36.2 million.

This Alien: Romulus Japanese Trailer Teases Far More Facehugger Horror

The latest look at the Alien prequel promises a sci-fi horror classic.

As it turns out, despite how lucrative theAlienfilms have been, none have cracked the $500-million mark at the box office globally, and sinceAliensnone have been universally acclaimed. It’s also worth noting that since the release ofAlien vs Predatorin 2004 — debuted 20 years ago — the Xenomorph has fared even better overseas than in the United States.

The fearsome Xenomorph and Facehuggers look ready to terrorize and reproduce inthe official trailer forAlien: Romulus.However, will the latest film in the sci-fi horror franchise be able to match or exceed the global box office totals boasted by the most lucrative entry in the series? The best worldwide total currently belongs toPrometheus($403.4 million). The other question that needs to be asked is: How much business willDeadpool & Wolverinesteal fromRomulus?
