Avengers: Endgame tickets went on sale Tuesday and Atom Tickets is reporting that in the first hour alone, the movie has set a record for the mobile ticket retailer, Deadline reports. Endgame has sold three times the tickets on Atom in the first hour of presales than Avengers: Infinity War sold last year.

It also outstrips presales for Star Wars: The Last Jedi. Fandango also reports strong sales, and some ticket buying sites (such as AMC) are crashing due to the high volume.

Disney’s Avengers: Endgame opens on April 26.
