Initially, directors Joe and Anthony Russo presented 'Avengers: Doomsday' as a standalone cinematic experience, implying viewers wouldn't need a deep understanding of previous Marvel Cinematic Universe (MCU) narratives. They famously coined the term 'phase zero,' suggesting the film would 'start over from scratch' and avoid leaning on past events. However, this assertion has been contradicted by the release of an official, extensive watchlist from Marvel and Disney Plus, unequivocally demonstrating that 'Doomsday' is intrinsically linked to the MCU's sprawling 18-year history, making prior viewing virtually essential for a complete understanding of the upcoming blockbuster.
The initial statements from the Russo brothers in June painted a picture of a fresh beginning for the MCU, aiming to make 'Avengers: Doomsday' accessible to both long-time fans and newcomers alike. They emphasized a departure from past storylines, fostering the idea that the film would be a standalone narrative requiring no prior 'homework.' This concept of 'phase zero' was intended to signal a new era, allowing the movie to carve its own path without the burden of intricate continuity. Yet, even at the time, skepticism arose due to confirmed appearances of key characters from across the MCU, including Captain America, Doctor Strange, Professor X, and Magneto, all of whom have significant established histories within the franchise.
This skepticism proved well-founded when Marvel, in conjunction with Disney Plus, unveiled a comprehensive watchlist for 'Doomsday.' This official list, designed to prepare audiences for the film's release, comprises a substantial collection of movies and series that span the breadth of the MCU. Among the titles included are foundational entries such as 'Captain America: The First Avenger' and 'The Avengers,' along with more recent additions like 'Loki,' 'Shang-Chi,' and 'Black Panther: Wakanda Forever.' Notably, classic X-Men films like 'X-Men' and 'X2' are also featured, underscoring the interconnectedness of various Marvel properties within the upcoming narrative. These inclusions directly refute the earlier 'phase zero' claims, making it clear that 'Doomsday' is deeply embedded in the cinematic universe's complex tapestry.
While many of the selections on the watchlist logically correspond to confirmed character appearances, certain omissions are quite intriguing. For instance, the absence of 'X-Men: Days of Future Past' is notable, given its thematic relevance to alternate timelines and multi-universe complexities that are often central to large-scale Marvel events. Another significant, albeit perhaps deliberate, omission is the Iron Man film series. With Robert Downey Jr. reportedly returning as Doctor Doom, the primary antagonist of 'Doomsday,' the exclusion of films featuring Tony Stark might be a strategic move to sidestep potential questions regarding the physical similarities between Doom and Stark, assuming the film intends to address or explain this connection.
With 'Marvel's Avengers: Doomsday' set to premiere on December 18, fans now have a clear roadmap to prepare for the film. The official watchlist, though extensive, provides both new and returning Marvel enthusiasts ample time to immerse themselves in the necessary storylines. This curated viewing experience ensures that audiences can fully appreciate the nuances, character developments, and overarching plot points that are expected to culminate in 'Doomsday,' reinforcing that the film is very much a continuation rather than a complete reset of the beloved Marvel saga.
