Atom toldDeadlineit sold three times as many tickets in the first hour of pre-sales as it did forAvengers: Infinity Warover the same timeframe last year. Pre-orders also outstripped first-hour sales forStar Wars: The Last Jedi. Fandango said it had strong sales too, so at least some people were able to endure the wait long enough to grab their tickets.
