December 18, 2026, will see two blockbuster events sharing the same evening: the long-awaited Avengers: Doomsday and the final chapter of the desert saga, Dune: Part Three. While the sand-filled popcorn bucket from the Dune opening has already sparked conversation, Marvel’s latest outing is matching the hype with a full suite of cinema-specific posters and a line-up of in-theater collectibles that differ from chain to chain.
Premium-format posters that give Doom a unique stage
Marvel Studios supplied a separate poster for each of the high-end exhibition formats. The Infinity Vision version shows Doctor Doom rendered in a stained-glass style, hinting at the format’s requirement for a screen at least 45 feet wide and laser projection. The Dolby Cinema artwork depicts Doom’s hand crackling with green energy, echoing the format’s emphasis on immersive sound and picture. ScreenX expands the visual field with cloaked figures flanking Doom, while the 4DX poster promises a seat-moving experience that mimics a simulator ride. A RealD 3D one-sheet simply announces the release date – “12.18.26 is Doomsday” – and a Fandango exclusive shows the villain perched on his throne. Notably, the film will not appear in IMAX; that space is reserved for Dune’s three-week run.
AMC’s collector’s cupboard: Doom buckets, Sentinel heads and team icons
AMC Theatres has rolled out the most varied merch set. The centerpiece is a Doctor Doom popcorn bucket shaped like the villain’s bust, complete with glowing green eyes. Alongside it, the chain offers a Sentinel head that doubles as a popcorn holder; the robotic Sentinel first appeared in X-Men #14 (1965) as a mutant-hunting device, now repurposed for snack time. An exclusive “Bottle of Doom” includes a fountain drink, and a trio of Team Icon buckets feature the logos of the Avengers, the X-Men and Doctor Doom himself. All items become available on December 17, but only while stocks last.
Regal’s throne-worthy treats and Sentinel beverage cups
Regal Cinemas mirrors AMC’s Doom bucket and adds two exclusive pieces. The first is the Doom’s Throne bucket, a larger vessel that invites fans to sit metaphorically upon Doom’s seat of power while munching on popcorn. The second exclusive is a drink cup perched inside a Sentinel head, allowing patrons to sip a soda while the robot’s eyes stare back. In addition, Regal will distribute limited-edition Marvel 3D glasses during a special screening on December 20 at selected locations. Members purchasing tickets through the Infinity Vision program can also receive a complimentary Magic: The Gathering “Avengers: Doomsday” card, subject to availability.
Cinemark’s LED-lit thunder: glowing buckets and refillable cups
Cinemark’s offerings lean into illumination. The chain presents an LED Doctor Doom Statue bucket whose eyes pulse with electric light, as well as an LED Doctor Doom 3D cup that mirrors the bucket’s design. Four additional souvenir cups are on hand, each paired with free same-day refills. Cinemark also supplies three distinct popcorn tins, all featuring Doom-themed artwork, giving fans multiple ways to show allegiance while the film rolls on the big screen.
When and where to experience the multiversal showdown
The official U.S. release is slated for December 18, 2026, but tickets are already on sale for a preview night on Thursday, December 17, at all participating chains. Moviegoers should act quickly, as pre-sale numbers have already eclipsed $100 million worldwide, indicating strong demand. For those who want to dive deeper into the Marvel and X-Men universes before the premiere, Disney+ now houses the entire MCU catalogue alongside the X-Men film library, providing a perfect primer before stepping into a premium-format theater.
