Walt Disney Company unveiled major Marvel expansions during its D23 presentation, detailing two new Avengers Campus attractions scheduled for a 2028 opening alongside a structured 41-hour cinematic preparation schedule for the upcoming Avengers: Doomsday feature film.

Disneyland California Adventure Expansions

The upcoming theme park additions, Avengers Infinity Defense and Stark Flight Lab, are slated to open at Disneyland California Adventure in 2028. Both rides integrate digital media and physical ride systems featuring core Marvel Cinematic Universe actors, including Robert Downey Jr. and Anthony Mackie. Stark Flight Lab utilizes a deployment system where pods are moved by robotic arms, mirroring Tony Stark's automated laboratory technology, while Avengers Infinity Defense centers on multidimensional travel to protect various Marvel locations from breaches.

The 41-Hour Doomsday Watch List

To prepare audiences for the narrative events of Avengers: Doomsday, Marvel Studios released an official chronological essential viewing marathon consisting of 14 feature films and one television series. Spanning a total runtime of 41 hours and 15 minutes, the curated curriculum begins outside the traditional MCU continuity with 2000's X-Men, establishing foundational multi-franchise continuity elements that Disney relies upon for the upcoming crossover event.

These simultaneous announcements establish Disney's dual-pronged strategy for the multi-year rollout of Avengers: Doomsday, aligning physical infrastructure investments in California with structured consumer viewing requirements ahead of the film's theatrical release.
