Marvel at D23 2026 is expected to headline the Disney Entertainment Showcase on Friday, August 14 at the Honda Center in Anaheim. Reporting points to a new Avengers: Doomsday trailer and a full X-Men cast announcement, though Marvel Studios has not publicly confirmed either. D23 runs August 14–16.

When Marvel’s D23 2026 panel takes place
D23: The Ultimate Disney Fan Event runs Friday, August 14 through Sunday, August 16, 2026, across the Anaheim Convention Center and the neighboring Honda Center.
The Disney Entertainment Showcase — the presentation where film and television announcements land — is scheduled for 7:00 p.m. PT on Friday, August 14 at the Honda Center. Per Disney’s official programming announcement, Honda Center presentations are restricted to Ultimate Fan Pass and Ultimate Preferred Fan Pass holders.
That access restriction matters more than it sounds, and we’ll come back to it.
The Avengers: Doomsday trailer
Multiple outlets report Disney plans to screen new Avengers: Doomsday footage at the showcase. Reporting also indicates the footage will be shown behind closed doors to attendees first, with an online release following at some later point.
As Screen Rant notes in its D23 preview, Marvel screened Doomsday footage at San Diego Comic-Con in July as well, so a D23 showing would be the second presentation of material to a live audience without a public release. Nothing about the online timing has been officially confirmed — treat any specific date you see as speculation until Marvel says so.
Our full Avengers: Doomsday guide covers the confirmed cast and release date, and we recapped every Marvel announcement from Hall H three weeks ago.

X-Men casting: what’s confirmed vs. what’s rumored
This is where most coverage blurs a line that’s worth keeping sharp. Here is the actual state of the X-Men casting as of August 11, 2026.
| Actor | Role | Status |
|---|---|---|
| Sadie Sink | Jean Grey | Confirmed — already appeared in Spider-Man: Brand New Day |
| Samara Weaving | Emma Frost | Reported as cast |
| Kit Connor | Cyclops | Reported to be in talks — not confirmed by Marvel |
| Bill Skarsgård | Professor X | Rumored shortlist only |
| Christopher Abbott | Professor X | Rumored shortlist only |
| Adam Driver | Unspecified villain | Rumored — role varies by report |
The Professor X situation is the murkiest. Trade-adjacent reporting has cycled through a shortlist that at various points included Skarsgård, Abbott and Tom Pelphrey, with Pelphrey later reported as out of the running. In the days before D23, several outlets converged on the same name — but converging rumors are still rumors, and Marvel has confirmed none of it.
Kit Connor’s Cyclops is the one most likely to move from “in talks” to official this week. We wrote about what the Connor reports actually said when they broke, and if you want the character context, our explainer on who Cyclops is and why he matters covers the comics history.
Why Marvel held the X-Men reveal for D23
Here’s the detail worth sitting with. Marvel had a Hall H panel at San Diego Comic-Con on July 25 — the single largest fan audience of the year, free to anyone in the room, covered live by every outlet on the floor. It announced Ryan Gosling’s Ghost Rider and Black Panther 3 there. It did not announce the X-Men cast, despite reportedly having at least two or three actors effectively locked at the time.
Three weeks later, that reveal is expected at a Disney-owned event, inside a venue gated behind a paid upgrade tier, with footage that reportedly won’t go online immediately.
That’s a choice, and it tells you how Disney is valuing the X-Men relaunch. Comic-Con generates goodwill; D23 generates ticket sales, Disney+ signups and a news cycle Disney controls end to end. A studio that thought of the X-Men cast as fan-service would have spent it in Hall H. A studio that thinks of it as a corporate asset spends it at its own event. Marvel is doing the second thing.
The practical consequence for anyone reading along at home: expect the casting news to arrive as text on social feeds within minutes, and expect the actual footage to stay locked behind the room for a while.
What else could appear
- VisionQuest — the Disney+ series is dated for October 14, 2026, which puts a trailer squarely in the launch window.
- Daredevil: Born Again — reporting suggests a possible look at the next season.
- Additional casting — beyond the X-Men, Marvel has several unannounced roles across its 2027–2028 slate.
None of the above is confirmed. We’ll update this piece once the showcase actually happens.
