‘Avengers: Doomsday’ Writer Just Teased the Scene That Might Wreck Everyone Emotionally

‘Avengers: Doomsday‘ has been building anticipation for months as one of the most ambitious crossover events Marvel Studios has ever attempted, bringing together an enormous ensemble under the direction of the Russo Brothers for a December 18 release. With a script credited to Stephen McFeely, Chris McKenna, Erik Sommers and Michael Waldron, the film carries the pedigree of some of the MCU’s most trusted writers, the same team responsible for shaping the franchise’s biggest crossover moments over the past decade.

Marvel has kept the film’s plot details tightly under wraps, as it typically does with any major ‘Avengers’ installment, leaving fans mostly reliant on cast announcements and occasional soundbites from the creative team to gauge what kind of movie this is shaping up to be. That secrecy makes any scrap of insider insight feel significant, especially when it comes from someone who actually helped write the thing.

That is exactly what happened when co-writer Chris McKenna sat down for an episode of The Bulwark Goes to Hollywood and gave listeners a rare glimpse into the film’s tonal ambitions. Discussing the story’s origins, McKenna credited fellow writer Stephen McFeely with the film’s foundational concept, saying, “Stephen had an idea for ‘Doomsday’ that is really great and really potent,” according to the post shared by The Hollywood Handle.

McKenna went further, describing how the film intends to balance massive scale with something more personal, explaining that it combines “big stars, big action, big movies, set pieces, big worlds” alongside “really intimate, small ideas, like character ideas.” That kind of dual focus has become something of a signature for McFeely’s collaborations with the Russo Brothers, who previously balanced sprawling ensemble stakes with quieter emotional beats in films like ‘Avengers: Endgame.’

Perhaps the most intriguing part of McKenna’s comments came when he touched on the emotional weight the film is aiming for, noting that the story contains “elements that are just fun and elements that are just really kind of an emotional gut punch.” Coming from someone with direct knowledge of the script, that kind of language has already sent fans into speculation mode about which characters or storylines might be responsible for delivering that punch.

He used to be different.

This is not the only project McKenna discussed candidly on the podcast, since the same episode also touched on his work on ‘Spider-Man: Brand New Day,’ suggesting the conversation offered a broader look behind the curtain at how Marvel’s writers rooms have been operating across multiple projects at once. That kind of crossover between writing teams tracks with how deeply interconnected the current phase of the MCU has become, especially heading into a film explicitly designed to tie together years of storytelling across separate franchises.

With ‘Avengers: Doomsday’ still a few months away from release, comments like these are likely to keep fueling speculation right up until the film actually hits theaters. Marvel has given very little away about the plot itself, but the promise of a story that swings between spectacle and genuine emotional weight fits the tall order this film has been tasked with delivering, following years of build-up across the current era of Marvel storytelling.
