With both Mummy and Camp Jurassic having their fire effects shut down temporarily, it could be because they are near construction sites? If the new nighttime show is receiving fire effects it could mean that they are connecting lines to Mummy's tanks?
Aside from that, Mummy still needs an update. It definitely is a "classic" Universal attraction that should remain in the park for at least 2-3 more decades. BUT it needs an update. A simple update involving:
-Expanding Tomb queue to the rest of it.
-Remove the entire "in a movie set" story and just make it an actual museum you are entering (where things go wrong)
-Update effects during the dark ride portions (everything from the station to the backwards drop is fine)
-Turntable, the only portion of the ride that is just embarrassing. Update projections and add rockwork or something that can hide the corners/end of the screen
-Coaster portions are great
-Change the "fake station" gag and just add more storyline (keep the fire)
-Change the finale to still being a tomb, remove the coffee, redress exit station as a tomb
They could simply give it an overhaul to match the Singapore version of the ride. Singapore is the EXACT same ride as Orlando, just with a slightly different take on the story. Yes, you're still fleeing from Imhotep because he wants your soul, but instead of looking for The Magi to save you, you're trying to find The Book of the Living (which he also wants, of course). The dialog throughout the ride is a mixture of the Orlando and Hollywood versions of the ride, as well as some unique-to-Singapore dialog thrown in as well. The scene where we first meet Imhotep is essentially the same (he harvests his first soul), but his victim is lying down, the animatronic animations are different and he's dressed in a hooded cloak. The turntable scene is a reverse of Orlando (it turns to the left instead of the right), but instead of the silly, TERRIBLE animation from Orlando, there are some fog curtains, "evil eyes" watching you in the distant darkness, and some hieroglyphics that light up on the walls as you turn. You then launch into the ride (with better strobing pics of Imhotep chasing you than either US version) and when you come to the "fake ending," it's just a scene where Imhotep is waiting for you. He tells you that "You will never stop me! Prepare to forfeit your souls! (evil laugh)" while he starts the ceiling on fire. Then it's the same short steep drop and brief run into the end brakes. However, instead of a video screen and Brendan Frasier waiting for you (cheesy), you come upon Imhotep's giant sarcophagus (suspended from the ceiling by ropes and shaking from the inside) as he tells you several different lines that differ each time ("Let me out!" "You can't keep me in here!" "You'll never keep the book from me!" "I'll be back!", etc.).
It's the same ride, with just a slightly different vibe to it. It's got a much more timeless feel than the (now) horribly dated Orlando version. If they toss the "movie set" theme to Orlando's ride and just make it a museum or an archaeological dig and extend the "Egyptian" theming to the very beginning of the line, it would do wonders to the ride. It would also be a pretty damn cheap overhaul too.
One area where Singapore's version BLOWS Orlando and Hollywood's versions away is the Queue line. For starters, the entrance is flanked by 2 giant stone statues (of Anubis?) that have to be 40' tall. They are absolutely MAMMOTH in size and dwarfed my tiny little Fiancee (who stands a
towering 4'9" tall)...she stood even with the tops of their feet (each one stands on 3' pedestals or so). The giant aspect continues through the queue line, with other huge statues and columns lining the walkway as you journey into the show building. For being a clone, it's damn impressive compared to the other versions they've done!
