Avengers: Endgame has already broken records. According to Fandango, the Marvel sequel has achieved more first-day pre-sales through the company than any other film, beating previous chart-topper, Star Wars: The Force Awakens.
Avengers: Endgame will be released in UK cinemas on 26 April.
In fact, the rush of fans attempting to buy tickets caused the website to crash, with fans claiming they had to wait more than an hour to buy tickets.
Many other ticketing systems in the US faced similar problems, including AMC Theatres, Regal Cinemas, and Atom Tickets.
