Marvel Studios and fast-food chain Jack in the Box have announced an unexpected promotional partnership tied to the upcoming blockbuster film Avengers: Doomsday. A promotional video shared across the restaurant’s social media channels introduces the “Doomsday Dipping Box,” a themed meal package that pairs fast-food menu items with promotional tie-ins for the sprawling cinematic crossover.
Beginning November 5, 2026, customers purchasing the promotional meal will receive an assortment of themed sauces alongside returning fan-favorite snacks. Each box also contains a randomly selected collector magnet packaged inside a blind bag. Fans will need to collect all eight available magnets to assemble the complete team of characters featured in the upcoming film.
According to a spokesperson for the restaurant chain, the collaboration aims to capture the scale of the cinematic event. A spokesperson stated that the campaign represents a larger-than-life expression of what happens when epic fandom meets unmissable food moments. The specialty menu features custom condiments including Assemble Sauce, Fantastic Buttermilk Ranch, and Mutant Marinara, accompanied by an additional mystery sauce marketed around the concept of “Doomsday meal prepping.”
The marketing campaign arrives as anticipation builds for the cinematic release, which is scheduled to hit theaters on December 18, 2026. The film is set to unite a massive ensemble cast by bringing together established heroes from the Marvel Cinematic Universe alongside characters from the Fantastic Four and the X-Men franchises for the first time on the big screen.
The star-studded roster features numerous returning performers from past Marvel projects. Notably, Robert Downey Jr., who previously portrayed Tony Stark and Iron Man, is slated to return to the franchise in the role of Doctor Doom. He will be joined by fellow MCU veterans including Chris Evans, Chris Hemsworth, Paul Rudd, Anthony Mackie, Florence Pugh, Wyatt Russell, Simu Liu, Sebastian Stan, and David Harbour.
The crossover will also incorporate the cast of The Fantastic Four: First Steps, bringing Pedro Pascal, Vanessa Kirby, Ebon Moss-Bachrach, and Joseph Quinn into the fold to reprise their respective roles. Furthermore, actors from 20th Century Fox’s legacy X-Men films are returning to their original superhero characters, including Ian McKellen, James Marsden, Patrick Stewart, Kelsey Grammer, Alan Cumming, and Rebecca Romijn, alongside Channing Tatum returning as Gambit.
Additional confirmed cast members rounding out the expansive ensemble include Letitia Wright, Lewis Pullman, Kathryn Newton, Danny Ramirez, Winston Duke, Hannah John-Kamen, Alex Livinalli, Hayley Atwell, Tenoch Huerta Mejía, Mabel Cadena, and Tom Hiddleston. As promotional efforts ramp up across both entertainment and commercial sectors, the December theatrical release remains one of the most highly anticipated cinematic events on the studio’s schedule.
