Commenters broadly agreed that ‘Avengers: Doomsday’ would dominate commercially if both films retained the date, with several users stating that the outcome was “not even a question” and predicting Marvel’s latest ensemble film would comfortably outperform Denis Villeneuve’s sci-fi epic.
A recurring view was that Warner Bros would be forced to shift ‘Dune Part Three’, either earlier into autumn 2026 or further back, to avoid a direct confrontation. Multiple users suggested October or November as more realistic windows.
Several contributors pointed to practical exhibition constraints, noting that both films are designed for IMAX and likely to exceed three hours. With limited IMAX screens, theatres would struggle to accommodate two such releases simultaneously, reducing daily screenings and revenue potential.
Others argued that Disney’s decision to begin marketing ‘Avengers Doomsday’ had effectively sealed the outcome, reinforcing expectations that ‘Dune Part Three’ would relocate. Some predicted the film could even move into early 2027, depending on post-production schedules.
While many conceded Marvel’s film would gross more worldwide regardless of quality, some users maintained that ‘Dune Part Three’ would likely be the superior film artistically, even if it failed to match Marvel’s opening weekend or overall totals.
A minority expressed fatigue with Marvel, calling the franchise “a shell of its former self”, though others pushed back, citing recent releases they considered successful and arguing that audience appetite for large-scale Marvel events remains strong.
There was also debate over which season best suits ‘Dune’, with December described by some as a poor fit for the franchise, while June was widely dismissed as too crowded and unrealistic given production timelines.
Despite differing opinions, the dominant consensus across the discussion was clear: releasing both films on the same day makes little strategic sense, and most expect ‘Dune Part Three’ to move, leaving ‘Avengers Doomsday’ uncontested on December 18, 2026.
