According to the OC Register’s Around Disney blog:
For the last week of the Disneyland Halloween fireworks, guests can see the spooky projections that go along with the show on mist screens in the Rivers of America.
Previously, visitors could only see projected images and animated characters, including host Jack Skellington, on a 20-foot orb on top of Sleeping Beauty Castle. Guests in other parts of the park, besides Main Street U.S.A., could not see the projections. The characters do the narration and songs that go along with the plot of the “Halloween Screams” show.
Now, guests can also see the full effects on the mist screens that are usually used for the Fantasmic! show in Frontierland, said John McClintock, a Disneyland Resort spokesman.
The fireworks show is scheduled in between showings of Fantasmic! over the weekend, meaning Fantasmic! viewers can stay in one spot to see both shows. On Friday, Saturday and Sunday, fireworks will be shot off at 9:25 p.m., while Fantasmic! appears at 9 p.m. and 10:30 p.m.
On Wednesday and Thursday, the fireworks show goes on at 8 p.m. Fantasmic! is only on weekends. The park is closed to the public tonight for a private party and there will be no fireworks.
Disneyland workers first showed the Rivers of America projections to the public on Thursday and decided to keep it through this weekend, McClintock said.
Light effects can be seen outside of the it’s a small world ride, but not the animated projections.
The last night of “Halloween Screams” is Sunday, when Halloween Time ends. This is the first year of the special Halloween fireworks show, which is expected to return next year.
