Avengers: Doomsday commands overwhelming presale momentum, with global advance tickets surpassing $100 million and domestic figures exceeding $50 million months ahead of the December 18 release, fueling projections for a $260–300 million domestic opening that dwarfs Dune: Part Three’s franchise-record tracking near $100 million. The MCU event film benefits from a star-studded ensemble led by Robert Downey Jr. as Doctor Doom, Russo brothers direction, and recent box-office momentum from titles like Spider-Man: Brand New Day, drawing a broader audience than the more specialized Dune fanbase despite the latter’s strong IMAX 70mm sellouts and critical pedigree. Marketing pushes and final tracking updates before opening weekend could refine the gap, though an upset for Dune would require exceptional reviews or unexpected audience shifts that current data does not support.
