Chris Hemsworth Joins Star-Studded Cast for Disney's Avengers: Infinity Defense

Marvel Studios president Kevin Feige used the D23 stage to announce one of the more ambitious theme-park undertakings in recent memory — a fully cast, narrative-driven experience that reads less like a ride announcement and more like a miniature MCU production. Chris Hemsworth is among the headliners, reprising his role as Thor alongside a constellation of returning franchise talent.

An All-Star Ensemble Assembled at D23

According to TheWrap, the new attraction — titled Avengers: Infinity Defense — is slated to open at Avengers Campus inside Disney California Adventure in 2028. Joining Hemsworth are Robert Downey Jr. (returning as Tony Stark, not the recently teased Doctor Doom incarnation), Jeremy Renner as Hawkeye, Anthony Mackie as Captain America, and Iman Vellani reprising her celebrated turn as Ms. Marvel, a role she first inhabited in the Disney+ series and carried into the theatrical release The Marvels. It is Vellani's character who will serve as the in-world recruiter, drawing park guests into the action as fresh Avengers Campus enlistees — a clever bit of narrative framing that positions the audience as active participants rather than passive observers.

Production Footage Shot Alongside Avengers: Doomsday

What makes the logistical picture particularly striking is that footage for the attraction was captured during the active production of Avengers: Doomsday, due in theaters this Christmas. The efficiency of that arrangement reflects how deeply Disney and Marvel have integrated their cinematic and experiential arms. The threat at the center of Infinity Defense involves King Thanos — a multiversal variant of the Infinity Saga's signature villain — which suggests the attraction will draw thematic threads directly from the broader storytelling happening on the big screen. For an actor like Hemsworth, who has been keeping busy between major franchise commitments, the opportunity to extend Thor's presence into an immersive format feels like a natural extension of the character's ongoing cultural footprint.

Stark Flight Lab Expands the Campus Further

The Infinity Defense announcement did not arrive alone. A companion attraction, Stark Flight Lab, was also confirmed for the same 2028 opening window and will feature Robert Downey Jr. and Anthony Mackie alongside Brie Larson, who returns as Captain Marvel. The pairing of two major new experiences effectively doubles down on Avengers Campus as a destination rather than simply a backdrop, suggesting Disney is investing substantially in the physical storytelling infrastructure around the MCU's next chapter.

Hemsworth's Expanding Creative Portfolio

For Hemsworth specifically, the attraction slots into what has been a notably diverse period professionally. Beyond the hammer-wielding work that defined his last decade, he has pursued projects far outside the Marvel orbit — from the action franchise work detailed in coverage of Extraction 3 moving forward with Hemsworth, Elba, and director Sam Hargrave to earlier genre experiments like Men in Black: International and its complicated streaming afterlife. Returning to Thor in a theme-park context, then, is not a retreat to familiar ground so much as another layer added to an already varied body of work.

What It Means for the MCU's Live Presence

Theme-park attractions have long served as a barometer for franchise health — George Lucas understood this when he shepherded Star Tours into existence in 1987, and Disney has refined the formula considerably since. The commitment of this many principal cast members to a single experiential project, with production woven into an active film shoot, signals that Marvel views Avengers: Infinity Defense not as ancillary merchandise but as genuine storytelling real estate. With 2028 still a few years out, the full scope of the attraction remains to be revealed, but the foundation being laid looks formidable.
