Okay so....Universal has an Alien vs. Predator haunted house at both of their parks, so obviously they were able to get the theme park rights for the Alien (owned by Fox).
However, we all know that Disney originally acquired the rights to the character back in the 1980s, with the intention of creating "Nostromo", a dark ride/show that would feature the alien attacking the guests. "Nostromo" had WDI in a tizzy, because that was just something you wouldn't find at a Disney park....so the idea was re-worked (with a tad bit of help from George Lucas) into the show we all know and love as The ExtraTERRORestrial Alien Encounter,
while the Xenomorph we all know and love was relegated to being a prop at the Great Movie Ride.
So my question is...did the rights to the Xenomoprh expire because Disney never did anything more with it? (see Roger Corman's low-budget "Fantastic Four", made solely for the studio to keep the rights)
Or is "Alien vs. Predator" considered a separate franchise from the mainstream Alien films?
And does the presence of AVP at Universal affect the Great Movie Ride, if a refurbishment should ever happen?
