On April 3, 2019, Fox's Emma Watts announced on CinemaCon that Disney has plans to continue the Alien franchise along with Kingsman and Planet of the Apes.
Alien is one of the movie franchises represented in The Great Movie Ride at Disney's Hollywood Studios. The guests enter the Nostromo during Ellen Ripley's confrontation with the Xenomorph, at which point the Xenomorph threatens the guests.
In addition, there had been plans to include another theme park attraction based on the Alien franchise, this would eventually evolve into the (now defunct) Tomorrowland attraction ExtraTERRORestrial Alien Encounter in the Magic Kingdom. The attraction was originally developed under the name of Nostromo, but eventually became its own independent property. Several analogues and counterparts between the attraction and films existed however such as: the Weyland-Yutani corporation with X-S Tech, the evil android Ash and S.I.R., executive Carter J. Burke with chairman L.C. Clench, and of-course, the ride's titular alien with the films' titular xenomorph.
