"Alien Day" was back in April, but really all that meant was some cool posters and other collectibles for fans to buy. April 26 wasn't an anniversary of any of the movies. It wasn't even a date referenced in the movies. The marketers that be just decided to interpret LV-426 (the name of the planetoid in the first film) as a date and go from there.
The real "Alien Day" of 2016 looks like it will be on July 23, 2016. That's when Comic-Con is putting on a special Aliens reunion panel in Hall H that will feature James Cameron, Sigourney Weaver, Bill Paxton, Lance Henriksen, Paul Resier, Michael Biehn, Carrie Henn (Newt) and producer Gale Anne Hurd. That's kind of a big deal considering Cameron typically avoids these kind of fan events. He's willing to make the exception for the Oscar-nominated Aliens, though, telling EW, "So looking at it retrospectively, you know, [Gale] and I both feel that was more of our graduation, or breakthrough, than Terminator — even though Terminator’s the film that put us on the map."
So that'll be a cool thing for fans at Comic-Con to hit up. Those of us who aren't going, however, are stuck thinking about the Alien franchise from a distance. At least there's plenty to think about, though. For example, Weaver confirms in that same EW piece that she's still talking to Neill Blomkamp about his proposed Alien movie. She even doubles down on the early buzz that it will be a fork in the mythology that ignores every film that came after Aliens.
The Blomkamp movie is still purely hypothetical, though. The next actual entry in the franchise will be Ridley Scott's Alien: Covenant, which is a sequel to Prometheus and yet still a prequel to the very first Alien. There is some minor news on that front, too, with Danny McBride talking to Rolling Stone a bit about the project. He's not able to say much since the movie is still filming in Australia, but he does reveal that he'll be playing the ship's pilot and that it's exciting to see Scott try to do everything as practical as possible.
"I didn’t know if it would be all green screen, but most of the stuff is practical effects. When you’re running from an alien it’s really a dude in an alien suit coming after you! The sets are incredible and you’re in them: We go through some inclement weather at one point on the spaceship and this whole gigantic set is on a gimbal, shaking up and down. You don’t have to use your imagination."
Alien: Covenant hits theaters on August 4, 2017.
