Outage reports for AMC’s mobile app jumped Tuesday after tickets for "Dune: Part Three" went on sale, with premium screenings such as IMAX and IMAX 70mm expected to sell out quickly. Resale activity appeared almost immediately, with some eBay listings offering IMAX 70mm tickets for $200 each. The rush echoes the earlier ticket release for "The Odyssey," when similar listings appeared and some sellers sought as much as $1,000. The ticket scramble comes as "Dune: Part Three" heads into a high-profile box office showdown with "Avengers: Doomsday," which opens the same weekend. While "Doomsday" will have broad screen availability, it will not play on domestic IMAX screens during its opening weeks because those auditoriums are reserved for "Dune: Part Three," which was partially shot for IMAX formats. The franchise has expanded its box office haul with each installment, from $410 million worldwide for "Dune" in 2021 to $714 million worldwide for "Dune: Part Two" in 2024. That momentum has raised expectations that the third film could surpass its predecessors, though its simultaneous release with "Avengers: Doomsday" leaves open whether the overlap will boost interest or divide audiences. Fans have already nicknamed the shared release date "Dunesday," pointing to the possibility of a double-feature event, much like the "Barbenheimer" effect that helped "Oppenheimer" reach $975 million globally and "Barbie" take in $1.4 billion in 2023.
