Ride begins rising up one floor. Doors open and a green light scans the riders and a white room in the foreground, similar to the thing that turned Bruce Banner into Hulk (the riders are "turning into Hulk"). Then the doors shut and the people sit in total darkness while the "elevator" rises yet another level. That is when the encounter happens and riders are shooting up and down whill a giant animatronic is grabbing at them, with explosions and effects happening all around them!
The Bourne series could also make a worthwhile attraction.
I'm shocked that nobody has made a zombie attraction. Universal has Dawn of the Dead (remake) among others, and could make a shoot-em-up ride. This ride wouldn't have scores and whatnot - your fate would be determined by your shooting. For example, if you shoot the zombie attacking the animatronic lady, you proceed to a laboratory, but if she dies you proceed to a warehouse. The ride could have so many different routes that the scares would never stop.
Another shoot-em-up ride that would be interesting is Hot Fuzz. I've wanted to reenact that final fight scene in Sandford since I saw the film in theaters. Arcade-style shooting in a small U.K. village would be too fun.
Personally, I'm still waiting on that Jurassic Park jeep ride. It could potentially be the greatest ride ever created. It would have to be indoors with strategic lighting so that the dinos seemed authentic (unlike those on the JP River Adventure). The pre-show could be like the movie pre-show with a rotating room showing the scientists working away. The beginning should be seemingly tranquil with beautiful landscapes and tiny little peeks at some of the inhabitants of the island. The guests approach the T-Rex paddock where a goat is chained up to lure him into view. The island then slowly clouds over and the power cuts out. A bolt of lightning on the right side of the car distracts the guests while the goat on the right disappears from view with a startling shriek. The next moment is then recreated from the movie, with the guests being in the shoes of the children. The T-Rex emerges, breaks the fence, and flips the car off the side of the wall. Guests experience a vertical drop (or simulated drop a la Spiderman) through a tree. At this point, some liberties would need to be taken with the original theatrical script. The guests jeep powers back on and is accelerated to 40 mph while outrunning the T-Rex. Naturally, it's pretty difficult to recreate a realistic T-Rex chasing a car, so some creative minds would need to create a tightly winding track surrounded by jungle through which the T-Rex could pop out in strategically placed locations. The rest of the ride could be high-speed trips through areas where the dinos have attacked (play with some of the movie deaths, like Gennaro in the outhouse), and climax at the Visitors Center with a raptor/T-Rex attack. Just dreaming here.
