The “Ghost Galaxy” Space Mountain overlay, which originally premiered at Hong Kong Disneyland in 2007, features a new soundtrack and ghostly and ghoulish projections inside the darkened roller coaster building.

The Halloween-themed fireworks show, hosted by “Master of Scaremonies” Jack Skellington of “Nightmare Before Christmas” fame, will include nods to Disney villains.  Many of those villains including Cruella de Vil (101 Dalmatians), Captain Hook (Peter Pan) and Queen of Hearts (Alice in Wonderland) will also be wandering the theme park, signing autographs and passing out treats.

Across the way at Disney’s California Adventure, “Mickey’s Trick-or-Treat Party” will run on Oct. 2, 8, 9, 15, 16, 21, 22, 23 and 28-31. The separate-admission event — which includes games, music and a Disney character parade — lets costumed children trick-or-treat throughout the park.

It is reported that the entire track will be replaced although the track layout will remain the same. The attraction’s will get a new queue area and a new treatment on the inside of its concrete ceiling.

The refurbishment is not expected to be as extensive or take as long as that of Disneyland’s Space Mountain which spanned two years.

MousePlanet suggested that “unless a sound system is added—increasing the weight of the cars—the support piers for the track should not need replacement.”

They also add that “with the back side of the show building being outside the berm, construction crews should be able to have unhindered access to work on the attraction without interfering with onstage appearances or backstage traffic.”
