Disney California Adventure has an exclusive sneak peek in the Sunset Showcase Theater which normally houses Mickey’s Philharmagic. The peek consists of explaining some of the origins of the Eternals on Earth as well as a trailer to conclude the preview. It makes use of lighting effects inside during key moments, though no other effects are used.
The lobby features several movie posters and graphics which lead guests to the waiting area. Right before the doors are displays of costumes of the characters from the film, like Angelina Jolie’s character, Thena’s, costume. The preview was present during the day and looks to be going on instead of Mickey’s Philharmagic for the time being. No indication on how long this will be in Disney California Adventure.
