Alien: Romulusis out now in theaters worldwide, much to the joy of many who had it listed as one of their most anticipatedupcoming moviesof the year. Set in-between the events of Ridley Scott’s Alien and James Cameron’s Aliens (two of thebest alien moviesever made), we follow a group of young scavengers as they face some familiar foes in what they believed to be an abandoned space station.
This is an Alien movie so to an extent you somewhat know what to expect, but Romulus also has some surprises in store including some various connections to the very divisive2012 prequel Prometheus- especially with the film’sjaw-dropping ending… Let’s dive into it!
Huge spoilers lie ahead for Alien: Romulus. And if you haven’t seen the film already, check out ourAlien: Romulus reviewfor our verdict as well as our guide to the bestmovies and shows to watch before Alien: Romulusif you want to prepare yourself before heading to the theater.
What is the compound and how does it connect to Prometheus?

With humanity struggling to survive in their various space colonies, Weyland-Yutani have created the ‘Compound Z-01’ using what they extracted from the xenomorph. Describing this as a “divine gift to humanity”, clearly the plan is to use this on people, with Rook urging our protagonists to take it back to the company for further development.
If you think this sounds familiar you would be right - in fact, we even get an explicit reference to the film where we have seen this compound before as Rook calls the discovery the “Prometheus file”.

Notably in Alien: Covenant we were introduced to ‘Steatite Ampules’, which are essentially urns designed to store the black goo and maintain a controlled environment for it. During the sequence in Alien: Romulus where Rook tells us about the compound, we see a hologram of one of these.
What is ‘The Offspring’?

Complete with a skeletal body, a sharp tail, and a second inner jaw just like a xenomorph, it really is quite something - and absolutely terrifying. Intriguingly, its face also resembles that of an Engineer from Prometheus, which tracks given The Offspring is partly born from the black goo featured in that movie.
Thankfully Rain takes it on in battle and defeats it, putting an end to the nightmare. However, given that other vials of the compound are in a storage unit on the ship and Weyland-Yutani knows of their existence, maybe we will see beings like The Offspring again in the future, especially if we get a potentialAlien: Romulus sequel.
Alien: Romulus is out in theaters worldwide now. For more sci-fi action, here’s how to watch theAlien movies in order, everything we know so far about the upcomingAlien TV series, and our favoriteAlien factsthat will blow your mind.
