It’s become tradition for most Marvel movies to have no other competitors on opening weekend, which often leads to big debuts at the US domestic box office and then notable drops in their second weekends. Spider-Man: Far From Home, however, is a slightly different case as the film opened on Tuesday, July 2nd, earning almost $93 million at the domestic box office before its first official three-day weekend in release, where it made $92.6 million. Far From Home remained the No. 1 movie at the North American box office this weekend, earning an estimated $45.3 million in its second weekend.
With a 51.1% decline in attendance, Spider-Man: Far From Home also had one of the lower drops in second weekend ticket sales for a Marvel Cinematic Universe film. (It should be noted, of course, that the Spidey solo films are distributed by Sony Pictures and not Disney like the main MCU entries.)
