Its most climactic box office battle came when The Fantastic Four: First Steps challenged the DCU launchpad in the same exact month. If Marvel Studios keeps that date on the calendar, we could be seeing a repeat of the July 2025 box office battle. Most Avengers-adjacent solo outings have received box office boosts from its association with the team-up attraction. However, less than a decade after Endgame, the theatrical landscape is shifting quite a bit, bringing much more uncertainty when it comes to box office expectations. The biggest winners are the core superhero movie fans, who will certainly love another July with Superman and a big MCU movie to look forward to.
