漫威工作室为了替预计于12月18日上映的《复仇者联盟：毁灭日》（Avengers: Doomsday）预热，在Disney+平台上推出了官方「毁灭日倒数」观影清单。这份精选清单共涵盖15部影视作品，旨在帮助影迷重温英雄起源、团队集结以及关键的多重宇宙概念，以便为全新大片的剧情设定做好准备。

该片单总时长约42小时，除了《复仇者联盟》系列与《洛基》等漫威电影宇宙作品外，还特别纳入了两部早于漫威电影宇宙的早期《X战警》电影，据传这是因为派崔克·史都华等原班演员有望回归，而2023年的《惊奇队长2》则未入选。此外，漫威还同步推出了官方每周回顾播客节目。

从商业角度来看，Disney+借由这份「观影作业」策略性地将即将上映的院线电影热度，成功转化为串流平台用户的观看时间与订阅留存率。清单上的所有作品均可在Disney+观看，部分作品亦可透过其他串流平台或在Amazon Prime Video与Apple TV上数位租借或购买。（关键数字：15）

Marvel Studios and Disney+ have introduced an official 'Countdown to Doomsday' playlist ahead of the December 18 theatrical release of Avengers: Doomsday. Featuring 15 curated titles, the playlist is designed to help fans revisit superhero origin stories, major team-ups, and essential multiverse lore necessary to fully grasp the upcoming blockbuster.

Requiring approximately 42 hours of total viewing time, the list includes MCU staples like Loki and the core Avengers films, as well as two early X-Men movies that predate the MCU, likely due to rumored returns of veteran cast members such as Patrick Stewart. Interestingly, 2023's The Marvels was excluded, while Marvel also rolled out an official weekly podcast recapping key story arcs.

Commercially, Disney+ is leveraging this preparatory watch list to channel cinema anticipation into active streaming engagement, effectively sustaining subscriber value leading up to the premiere. All 15 featured selections are available on Disney+, with various titles also accessible across other digital rental and streaming platforms like Apple TV and Amazon Prime Video.
