Marvel Says 'Endgame Encore' Is Required Viewing Before 'Doomsday' — Here's Why

Marvel Studios is turning a re-release into a homework assignment. The studio's theatrical return of Avengers: Endgame, rebranded as Avengers: Endgame Encore, isn't just a nostalgia play — it's loaded with new footage that director Joe Russo describes as required viewing ahead of Avengers: Doomsday, which hits theaters December 18, 2026.

The encore edition adds several brand-new scenes, and they are not filler. The most talked-about moment sees Loki appearing at the door of Steve Rogers and Peggy Carter's home — a stinger that directly implicates the God of Mischief's timeline meddling in the new saga. A mid-credits scene reportedly shows Doctor Doom abducting Bruce Banner, planting a flag for the next Avengers villain in the most literal way possible.

The TVA Sequence Changes Everything

Perhaps the biggest addition is a sequence set at the Time Variance Authority showing the multiverse actively collapsing. Fans of Loki's Disney+ series will recognize the setting immediately — and the new footage reportedly makes the show's second season essential context rather than optional streaming homework. If you've been sleeping on the TVA storyline, the encore is Marvel's way of making sure you catch up before December.

That framing is a bold move from Marvel. Rather than pretending continuity doesn't matter, the studio is leaning into it, positioning the encore as a bridge between the Infinity Saga and whatever Doom has planned. Russo's "required viewing" comment is half marketing, half genuine: the new scenes reframe Endgame's ending as the opening chapter of a much bigger crisis.

What This Means for Doomsday

Avengers: Doomsday arrives in under three months, and Marvel's marketing machine is clearly ramping up. The encore's new footage answers — or at least teases answers to — several long-standing questions: why Loki is back in the picture, what Doom wants with Bruce Banner, and how quickly the multiverse is falling apart.

The Bruce Banner abduction is particularly intriguing. Doom targeting one of the original six Avengers suggests the villain's plan is personal, not just cosmic. And with the TVA watching the multiverse crumble in real time, the stage is set for a film that treats the last several years of streaming and theatrical storylines as one continuous thread.

Whether the encore's additions justify a theatrical return for a movie most fans have seen multiple times is a personal call. But as a hype delivery device for Doomsday, it's undeniably effective — and the box office numbers suggest audiences agree. Either way, December 18 can't come soon enough.

The re-release strategy also says a lot about where Marvel is in 2026. Rather than asking audiences to rewatch a dozen streaming series before December, the studio is packaging the essential context into a single theatrical event — a smart concession to the reality that even dedicated fans can't keep up with everything. If the encore's new scenes deliver on their promise, it could become the rare re-release that actually matters to the story going forward.
